Claims (1)
過フィルタ、交流増巾回路およびシュミット回路を順次
接続してデータ信号処理を行なうＦＭ受信機において、
前記低域通過フィルタのカットオフ周波数をデータ信号
を通過させるに必要な帯域より充分高く設定し、データ
信号と無人力時出力信号との出力パルス巾の差をつける
如くして成るＦＭ受信機。In an FM receiver that performs data signal processing by sequentially connecting a low-pass filter, an AC amplifying circuit, and a Schmitt circuit to the FM demodulation circuit of the superhetero gain receiving circuit,
The FM receiver is configured such that the cutoff frequency of the low-pass filter is set sufficiently higher than the band required to pass the data signal, and a difference is created between the output pulse widths of the data signal and the unmanned output signal.
