摘要： A remote control signal reproducing circuit for use in a remotely-controlled receiver which receives a modulated transmission signal subjected to a pulse modulation, reproduces an original remote control signal form the received modulated transmission signal, and judges the reproduced remote control signal for effecting predetermined control operations based on pulse counts obtained during three predetermined successive time intervals.A remote control signal is delivered if the pulse count obtained in the first time interval exceeds a first level. Judgement of the remote control signal is stopped when the number of pulses counted during the second and third time intervals is below or above predetermined numbers respectively. The circuit functions to eliminate noise pulse.
