Document Type and Number:
Japanese Patent JPS634977
Kind Code:
B2
Abstract:
A receiver utilizing a switched capacitor filter is disclosed. The switched capacitor filter has a band pass determined by a control signal applied thereto. A waveform shaping circuit generates the control signal as a function of a received signal which has been modulated in angle and amplified. The wave shaper generates the control signal only when the amplified signal is above a predetermined value and generates the signal at a frequency which causes the switched capacitor filter to operate at the correct band pass.
