Abstract

PURPOSE:To obtain a high-gain two-way amplifier having the signal discriminating capacity, by providing a balancer and a transmission/reception line across a commutator connected in the adverse direction. CONSTITUTION:An aural signal is supplied at point A, and a high frequency pulse is supplied at point B. When a transistor (TR) conducts, capacitors C1 and C2 are charged through diodes D1 and D2, while the electric charge which is charged to the C1 and C2 is discharged via choke coils ch1 and ch2 of a filter circuit, capacitors C3 and C4, a balancer ZB and a transmission/reception line ZT respectively to transmit the signal to the line ZT when the TR does not conduct. At the same time, the signal sent through the line ZT is extracted at a point P2 via a filter. Then the received signal is extracted through a band pass filter BPF.
