摘要： Techniques are described that can be used to reduce interference in a desired channel by one or more other channels. A radio includes a level detect logic that is responsive to both the frequency offset and amplitude of undesired signals and sets the gain applied to received signals based on the offset frequency and determined amplitude of undesired signals. For example, detection of a signal amplitude in an interfering signal in a channel adjacent to the desired channel may be made. Detection of a signal amplitude in an interfering signal in a channel other than the adjacent channel and desired channel may also be made. Based on detection of one or more interfering channel, a gain of an input signal may be adjusted. Interference arising from at least spectral re-growth of noise and clipping noise may be reduced.

摘要： Generally speaking, methods and apparatuses which correct errors related to phase and gain imbalances in quadrature tuners are disclosed. The quadrature tuner may be online and operating, receiving data. An embodiment may generate a squared signal from the IF frequency signal of the tuner. In generating the squared signal, the embodiment may enable the extraction of phase error and gain error information of the IF signal. The embodiment may determine a phase error component, a gain error component, or both, by frequency translation. The frequency translation may involve down-converting the signal associated with the error component to direct current (DC) signals and enable the determination of the associated phase error and/or gain error. The embodiments may generate an adjusted signal via the IF signal by applying a phase correction signal or gain correction signal to components used to correct the IF signal.

摘要： A frequency changer for a radio frequency tuner and a tuner incorporating such a frequency changer are provided. The frequency changer comprises a mixer comprising a plurality of mixing stages. The output signals of these stages are supplied without relative phase shift to a summer, for example, in the form of a common load arrangement. The inputs of the stages are connected together to form a signal input of the mixer. Commutating signal inputs of the mixing stages received from the local oscillator are of the same frequency, but of different phases. The commutating signals are square or rectangular waves.

摘要： Apparatuses, systems, and methods that align channel filters for dual tuners are disclosed. An embodiment may comprise an IC having two tuners. Each tuner may have a low-noise amplifier, a mixer with a local oscillator, and channel filter. To perform a channel filter alignment, a bandwidth controller may cross-couple the local oscillator of each tuner to the input of the mixer of the opposite tuner. The bandwidth controller may adjust the frequencies of the local oscillators to produce different configuration tone frequencies at the outputs of the mixers, which are inputs to the channel filters. The bandwidth controller may then determine an amplitude difference between two separate measurements of a channel filter output and, based on a comparison of the measurements with predicted values, increment or decrement the filter bandwidth for each tuner and store parameters for the channel filters which create the largest signal amplitudes.

摘要： A pulse generator is provided for generating pulses with a selectable variable width and/or delay. The pulse generator comprises an oscillator and a selecting arrangement for selecting how many of a first group of delay elements are connected in series for delaying the oscillator signal. Identical delay elements are connected in series to form a second group. A measuring circuit repeatedly measures the delay provided by the second group, for example providing output pulses whose width or duration is equal to the delay. A reference pulse generator generates a series of reference pulses, each of which is a predetermined fraction of the oscillator period. A control circuit compares the measurement and reference pulses to generate an error signal that is fed back to timing delay control inputs of all the delay elements such that the widths of the measurement and reference pulses are made substantially equal to each other.
