摘要： A method for estimating a property of a signal (1) sensed in an electrical system, comprises the steps of sensing the signal (1) and estimating a fundamental period of a fundamental of the signal (1) by comparing the sensed signal (1) with at least one threshold (2) to detect threshold crossings and estimating the fundamental period from the threshold crossings. The signal property is then estimated from the fundamental period and/or from the sensed signal (1) during an interval of a length of the fundamental period.An electronic device according to the invention comprises a micro controller and/or an analogue circuitry which performs the method for estimating a property of a signal. Preferably, the micro controller and/or analogue circuitry controls other parts of the electronic device depending on the results obtained by the method for estimating a property of a signal.

摘要： A digital measurement system includes an oscillator, a mixer, and a controller coupled to each other. The oscillator provides a reference signal having a second frequency. The mixer generates a down-converted signal based on the output signal and the reference signal. The controller then determines a characteristic of the output signal (e.g., frequency or phase) based on the down-converted signal. An analog measurement system includes a filter having a center frequency, a rectifier, and a controller. The filter filters the output signal and the rectifier rectifies the filtered signal. The controller samples the rectified signal and determines a characteristic of the output signal based on the level of the rectified signal. The reference signal controller may adjust a characteristic of the output signal based on the determined frequency and/or phase of the output signal.

摘要： This invention describes a method by which Broadband Spectrum Analysis can be performed in the RF and Microwave frequency range with significantly higher speed, accuracy, and flexibility than existing RF and Microwave Spectrum Analyzers. This is done by eliminating the need for the filtering of the incoming signal, a process called preselection that needs to track in frequency with the scanning local oscillator in the instrument. By eliminating this requirement, this invention makes possible the identification and analysis of very broadband signals in a single sweep using an Adaptive Sweep Methodology and a Simultaneous Sweep capability that the present invention makes possible.

摘要： Method for frequency detection and detecting variation of frequency is disclosed. The method comprises the following steps. First of all, a pointer is provided over an electromagnetic position detection apparatus, wherein the pointer emits an electromagnetic signal with a frequency f1. Next a base integration signal is generated according to the integration of the electromagnetic signal with the frequency f1 for a current integration period x. Then a current integration signal is generated according to the integration of the electromagnetic signal with the frequency f1 for the current integration period x and a predetermined electromagnetic signal with a predetermined frequency f0 for the predetermined integration period y. Finally, a frequency variation value Δf between the frequency f1 and a current frequency fc is calculated and obtained according to the current integration signal and the base integration signal.
