Abstract
A method and apparatus for controlling the feedback path in a signal conditioning system. An input signal having signal pulses superimposed on a first d. c. voltage level is applied to a signal conditioner to generate conditioned signal pulses superimposed on a second d. c. voltage level established by a feedback circuit. A first comparator generates a constant magnitude output pulse during the time that the magnitude of a signal pulse exceeds the magnitude of a first reference voltage. The output signal is differentiated and a second comparator generates a control signal during the time the magnitude of the differentiated signal exceeds the magnitude of a second reference voltage. A transistor switch is responsive to the control signal for interrupting the feedback path during which time capacitor means continues to establish the second d. c. voltage level while the signal pulse is conditioned by the signal conditioner.
