Abstract
A noise reduction circuit which operates on the principle of coring includes a variable offset potential source in series with one diode which is connected antiparallel with a second diode. The output terminal of the parallel circuit is connected to an integrating capacitor so that the turn-on potential of the diode circuit floats with the output potential. The variable offset potential source is responsive to the output potential to apply varying forward or back bias to one of the diodes and thereby change the coring threshold of the diode dependent upon signal amplitude. The variable offset potential source consists of a resistor connected between two variable current sources configured to provide equal currents of opposite polarity thereto. A digital implementation is also included.
