Abstract
A threshold extension device for use in a frequency modulation demodulator circuit to minimize effects of impulse noise, usually referred to as 'clicks', which normaly appear in the demodulated output signal, and including a delay line for delaying the demodulated signal, a follow and hold circuit for selectively omitting the click impulses from the delayed signal, a detector for detecting the occurrence of an event which will give rise to a click impulse in the demodulated signal, and a detector driven control signal generator for controlling operation of the follow and hold circuit.
