Abstract

　データ信号の受信を検出したとき電源制御開始信号を発生すると共に一定時間後に信号処理部へ該データ信号を出力し、該電源制御開始信号が発生してから該信号処理部から処理完了信号を受けるまで、該信号処理部の電源の出力電圧変動を抑制するための電源制御信号を発生する。或いは、受信したデータ信号を種類別に分離して各々の信号処理部に出力し、該種類別の有効設定信号を受けると共に該有効設定信号が重複して有効になったとき、電源制御開始信号を発生し、該電源制御開始信号が発生してから、今まで有効であった該有効設定信号の一つが無効になるまで、該信号処理部の電源の電圧変動を抑制するための電源制御信号を発生する。
