Patent ID: 8872690

Claim:
A signal quantization system, comprising: an electronic circuit configured to receive an analog signal, and to selectively produce in dependence thereon a quantized representation of the analog signal having a logical state; an amplifier configured to receive the quantized representation of the analog signal, and to selective produce in dependence thereon an amplified quantized representation of the analog signal having an analog signal power corresponding to the logical state, wherein the amplified quantized representation of the analog signal is delayed relative to the analog signal; a time synchronization structure to reduce a relative time delay between a delayed representation of the analog signal and the amplified quantized representation of the analog signal; an electronic element configured to generate a signal corresponding to a quantization error, representing a difference of the delayed representation of the analog signal and the amplified quantized representation of the analog signal; an electronic circuit configured to receive the signal corresponding to a quantization error, and to selectively produce in dependence thereon a quantized representation of the quantization error; and a digital processor, configured to process the quantized representation of the analog signal and the quantized representation of the quantization error, and to generate a composite logical signal.
