Abstract
A circuit for providing a signal which is clamped to a desired DC voltage level comprises an amplifier for receiving an input signal and a feedback loop for developing an offset signal for combination with the input signal by the amplifier to provide an output signal at the desired DC voltage level. The feedback loop includes a noise detector for detecting the level of noise present in the output signal, and adjusting the time constant of the feedback loop in dependence thereon.
