Abstract
A noise pulse suppression system for a receiver comprising holding means for holding an input signal level which precedes immediately the appearance of a noise pulse for a predetermined time duration upon appearance of the noise pulse in an input signal, subtracting means for determining the difference between the input and output of a delay circuit for delaying the input signal or a difference between the delayed output and an output obtained by holding the delayed output for a predetermined time duration, and adding means for adding a correcting signal obtained from the subtracting means to the output of the holding means. The circuit suppresses noise pulses in the input signal and does not generate additional noise.
