Abstract
An analog to digital conversion system is disclosed which converts an analog signal to a digital representation thereof at a first sampling rate by distributing the analog signal to at least two signal paths, at least one signal path including a limiting mixer to mix the signal with a respective selected square wave and a smoothing (low pass) filter to filter the mixed signal before providing the mixed and filtered signal to a subconverter, the subconverter having a sampling rate less than the first sampling rate, and a digital matrix filter to combine the digital output of each subconverter to form a digital representation of the analog signal as sampled at the first rate.
