  • Method and apparatus for estimating and digitizing instantaneous frequency and phase of bandpass signals
    Patent number: 6456950
    Abstract: The present invention is a method and apparatus to detect an instantaneous frequency of an input signal. A sampler samples the input signal to generate a sampled signal. A metric generator is coupled to the sampler to generate a metric signal based on the sampled signal. The metric signal has a magnitude proportional to the instantaneous frequency of the input signal. In another embodiment, the apparatus comprises a feedback circuit and a decimator. The feedback circuit generates a sequence signal from the input signal. The sequence signal represents a change of the instantaneous frequency of the input signal. The decimator is coupled to the feedback circuit to decimate the sequence signal to generate a frequency signal. The frequency signal providing the instantaneous frequency of the input signal.
