ABSTRACT:
A generalized frequency modulation (FM) based method for converting an analog signal to a digital signal. An analog input signal is sampled at the Nyquist rate. Each sample is converted to a corresponding modulated chirped FM signal. The digital signal is generated by sampling each modulated chirped FM signal at a rate which depends upon the bits per sample of the analog-to-digital (A/D) converter.
