摘要： A telephone line interface which performs the BORSHT functions employs pulse width modulation and eliminates dc in the transformer to reduce the size of the coupling transformer thereby reducing space and costs. The ring function is provided to the subscriber without use of mechanical relays. An automatic, dynamically adjusted hybrid network is provided for removing echo signals thereby providing major improvement in two-to-four wire conversion performance. The circuitry lends itself to large scale integration thereby reducing space and cost and improving reliability.

摘要： An adapter for a direct broadcast television system enables owners of existing dish antennas to receive both current analog television broadcasts and new digital television broadcasts via C-Band satellites. The adapter includes a coaxial switch for switching between analog and digital television, a tuneable demodulator for selectively switching between transponders on the C-Band satellites, a channel selector unit for selecting the channel specified by the user from the bit stream output by the demodulator, a channel expander for decompressing the video signal, and a control unit for accepting user commands and controlling the polarization of the received signals, the steering of the TVRO antenna, the demodulated transponder frequency and the demultiplexed channel. The ability to select the user's channel from multiple channels available on different transponders and different satellites allows the dynamic reassignment of television channels based on system efficiency considerations. The adapter described herein permits a smooth transition from existing television service to a new digital C-Band television service, without requiring a new antenna or removal of the existing antenna. The device is able to simultaneously serve analog and digital TV to both cable and TVRO and C-Band small antennas and enables a smooth, seamless conversion to digital C-Band receivers with only one box. In addition, the system design minimizes satellite costs and equipment conversion costs. Rapid change to 8 channels per transponder for TVRO and cable is then followed by reduction to 3 and 4 channels to permit use of small C-Band antennas without interrupting service to existing customers.

摘要： A C-Band or Ku-Band satellite communication system uses a relatively small receiving antenna while operating within current FCC designated bandwidth and using existing satellite configurations. Aperture synthesis techniques create nulls in orbit locations from which potential interference is expected. Bandwidth inefficient modulation techniques reduce transmission power flux density. Video compression reduces the power necessary to transmit video information. These three features make possible a receiving antenna with a receiving area equivalent to that of a three foot diameter dish, at C-Band frequencies. Comparable reductions are possible for Ku-, Ka-, Sand L-Band systems. Compressing the data reduces the required transmitted power by a factor of ten. Spreading the bandwidth reduces the power density below the FCC limitation. However, reducing the antenna diameter increases the beam width of the antenna, hence, the smaller antenna can no longer discriminate between adjacent C-Band satellites in their current orbital configuration. By designing the receiving antenna with nulls in orbital locations where potentially interfering satellites would be located, the small antenna avoids this interference. The same general technique is possible for a Ku-Band Antenna system. The FCC power limits are higher at Ku-Band than C-Band, however, losses due to rain absorption and thermal noise are higher at Ku-Band frequencies. Nevertheless, equivalent size savings on Ku-Band antennas are possible with the combination of the above techniques, when tailored for the Ku-Band environment.

摘要： An electrical transmission line has improved signal transmission characteristics, low attenuation, constant phase and group velocity and constant and nearly ohmic characteristic impedance over a wide frequency band by providing low magnetic loss inductance along with the shunt capacitance of the insulation surrounding the conductors. The low loss inductance can be provided by particulate magnetic material, such as ferrites, homogeneously distributed in the insulating material or alternatively the inductance can be provided by ring(s) of magnetic material concentric with the conductor or by layer(s) of magnetic material when the conductor(s) are flat. A variety of radial or longitudinal profiles of the doping level is possible and can be used in combination with any of these basic loading designs. These concepts can be applied in twisted pair, coaxial or high voltage power transmission and distribution single or three phase cables or strip lines and other breadboard applications. A set of additional designs which incorporate the magnetic loading in the conductor occupied region is also proposed, with one application being the high voltage or large size cables. The so designed twisted pairs have performance comparable to existing coaxial cables. All lines have superior performance than the conventional ones at virtually the same cost. Magnetic loading of existing cables and overhead lines is also disclosed.

摘要： A CMOS Class F amplifier uses a differential input to eliminate even-order harmonics, thereby avoiding the need for circuits that are tuned to the second harmonic. This also minimizes the sensitivity of the design to changes in the second harmonic frequency and/or the particular component values selected for the tuned circuit. Third-order harmonics are reduced by controlling the phase relationship between the differential inputs. Additional efficiency is achieved by dynamically controlling the impedance of the amplifier as a function of output power level.

摘要： A receiving antenna includes a parabolic reflector and a feed horn. The feed horn includes an electrically conductive wall with an edge forming an aperture. The feed horn further includes a plurality of electrical conductors that extend from the edge to the center of the feed horn in a substantially coplanar relationship with the aperture. Each of the electrical conductors differentially affect a first polarized electrical field perpendicular to the edge adjacent the electrical conductor and a second polarized electrical field parallel to the edge adjacent the electrical conductor. In this manner, the electrical conductors can be configured to reduce the effective aperture of the feed horn in a plane, so that a first polarized horn radiation pattern produced by the feed horn can be circularized. The electrical conductors with respect to a vertical plane preferably match the electrical conductors with respect to a horizontal plane, so that first and second polarized horn radiation patterns produced by the feed horn can be simultaneously circularized. Another receiving antenna includes a splash plate and a feed horn that respectively include opposing edges that form an annular aperture. The feed horn further includes a plurality of electrical conductors that extend from the feed horn edge towards the splash plate edge in a coplanar relationship with the aperture. Again, the electrical conductors can be configured to reduce the effective width of the annular aperture in a plane, so that a first polarized horn radiation pattern produced by the feed horn can be circularized, while at the same time a second polarized horn radiation pattern produced by the feed horn can be circularized.

摘要： An RF communications receiver permits greater integration on standard silicon chips and consumes less power than previous receivers. Sub-sampling and discrete-time signal processing techniques are used to frequency down-convert, filter, amplify, and select a desired analog RF channel. A sample-and-hold circuit sub-samples the desired analog RF channel of carrier frequency f.sub.c, thereby down-converting it to a discrete-time image signal of frequency f.sub.i. Successive down-sampling, anti-alias filtering, and amplification of the discrete-time image signal yield a low-frequency discrete-time signal containing a down-converted channel of frequency f.sub.k. The low-frequency discrete-time signal is then digitized, filtered, and demodulated to reveal its baseband information content.
