ンデンサを並列接続した信号トラツプ装置。 A series circuit of a trap circuit and a switching transistor is interposed between a signal transmission path and a reference potential point, and a base bias of the switching transistor is turned on and off to turn on and off the trapping operation of the transmission signal by the trap circuit. A signal trap device further includes a capacitor for reducing base impedance connected in parallel between the base and emitter of the switching transistor.
