Title:
MEASURING CIRCUIT FOR WAVEFORM WIDTH OF REMOTE CONTROLLING SIGNAL
Document Type and Number:
Japanese Patent JPH04248475
Kind Code:
A
Abstract:
PURPOSE: To obtain a circuit for measuring waveform width of remote controlling signal for exactly measuring the waveform width.
CONSTITUTION: A receiver means 10 for receiving remote controlling signal consisting of at least one pulse, an amplifier means 20 for wave-shaping and amplifying the remote controlling signal, a counter 30 for counting a clock cleared and input, a gate means 40 for providing the clock with a gate and a microprocessor 50 for calculating the waveform width of the remote controlling signal, are provided. By this, the remote controlling pulse is detected with a counting method, so the pulse width of the remote controlling signal can be exactly measured regardless of the exterior interference.
