Abstract
Improvements in compressors, expanders and noise reduction systems are disclosed which reduce the susceptibility of such circuit arrangements to undue control by signals outside the pass-band(s) (i.e., stop-band signals) in which the circuits are active. Level dependent circuitry operates, particularly by means of non-linear processing, to reduce the circuit response to the effect of stop-band signal components at high input signal levels.
