Abstract
System and method for converting a high bandwidth analog signal to a digital signal including: receiving the high bandwidth analog signal; splitting the high bandwidth analog signal to M parallel channels; delaying the split signal in each channel with N*T delays, respectively; sampling each M delayed signals by M relatively prime sampling rate, wherein the sampling rate for each M delayed signal is smaller than the Nyquist frequency of the high bandwidth analog signal; upsampling each M sampled signal, wherein the upsampling rate for each M sampled signal satisfies the Nyquist frequency of the high bandwidth analog signal; combining the M up sampled signals into a combined signal; and reconstructing the combined signal to generate a digital signal representing the high bandwidth analog signal.
