Abstract
PURPOSE:To directly connect the titled circuit to a computer by making both diodes conductive or nonconductive when no control signal is applied to a control input terminal. CONSTITUTION:In case of applying a control signal to a control input terminal 4, when a pulse signal fed to an input terminal 2 exists, for example, a diode 10 of other end 7b of a primary winding 7 of a high frequency transformer 6 is conductive and a diode 9 at the other end 7a is nonconductive. A carrier from a sinusoidal wave oscillator 5 applied to an intermediate tap 7C of the high frequency transformer 6 goes to a capacitor 18 and earth from a diode 10 at the other end 7b being conductive. Thus, a voltage (0 phase) in phase with that at the primary winding 7, for example, is induced in the secondary winding 8 of the high frequency transformer 6 and sent from an output terminal 3. When no control signal is applied to the control input terminal 4, both the diodes 9, 10 are either conductive or nonconductive independently of the presence of the pulse signal fed to the input terminal 2. Thus, the input terminal 2 is directly connected to the computer.
