Abstract
An improved squelch circuit and methodology for a multi-level quantizer employing one or more amplifiers to amplify an input signal at different gains. Comparators coupled to corresponding amplifiers or amplifier stages produce pulses based on comparing the amplified signals with a common reference potential. Digital delay lines coupled to the comparators repeatedly delay the pulses.
