Claim Text:
1. A signal processing system, comprising: an input configured to receive an analog signal; a first electronic circuit configured to selectively produce a stream of quantized pulses which represent an amplitude of the received analog signal delayed with respect to the analog signal; a time delay structure configured to control a time delay of the received analog signal with respect to the stream of quantized pulses, and producing a delayed received analog signal; a second electronic circuit configured to selectively produce an analog residue signal representing a difference between an amplitude of the delayed received analog signal and the represented amplitude of the received analog signal; a third electronic circuit configured to selectively produce a quantized representation of the analog residue signal; and a digital signal processor, configured to receive the stream of quantized pulses and the quantized representation of the analog residue signal, and to generate a signal representing the amplitude of the received analog signal with an accuracy greater than the stream of quantized pulses.
