NOISE SIGNAL CONTROL PROCESSING METHOD OF A REMOCON RECEPTION SIGNAL

摘要

PURPOSE: A noise signal control processing method is provided to prevent a malfunction of a system by easily recognizing a noise. CONSTITUTION: The noise signal control processing method comprises the steps of: calculating a timing from a rising edge to a falling edge of a remote reception rectangular wave demodulated from a waveform shaper; detecting whether the calculated value is less than 1/maximum frequency of a remote control signal; recognizing the remote controller reception rectangular wave as a noise signal when the calculated value is less than 1/maximum frequency of a remote control signal; and recognizing the remote reception rectangular wave as a control signal when the calculated value is higher than 1/maximum frequency of a remote control signal.
