摘要： Asynchronous electrical circuitry (400, 500, 600, 700, 800, 900) produces a stationary carrier signal (470, 470') and encodes a system input signal (460, 460') amplitude into output signal time-sequence information by establishing at a digitizer (410, 510, 610, 710, 810, 910) an operating point value (416, 516, 616, 716, 816, 916) as an average amplitude of the system input signal. It applies to the digitizer a multicomponent digitizer-input signal (470, 470') corresponding to a sum of a passband signal component and a feedback signal component to produce a pulse-width modulated digitizer output signal (480, 480') representing the system input signal. An asynchronous time delay (t(s)) is introduced to produce the pulse-width modulated system output signal (y(s)). The circuitry performs digital to analog conversion (DAC) to the pulse-width modulated system output signal to produce a DAC output signal (490, 490'). The DAC output signal or its summation with the passband signal component is integrated to produce the feedback signal component. Additional, multiple-order embodiments include sequential feedback paths or carrier-shaping functions.
