摘要： PURPOSE:To realize size reduction and economization by allowing a hybrid transformer to function as a two-wire/four-wire converting circuit and an eliminating means for an in-phase noise generated between both lines of a two-wire commuication circuit and the ground. CONSTITUTION:The two-wire/four-wire converting circuit consists of the hybrid transformer 7; and a balanced connection network 8 is connected to the neutral point of a four-wire side winding 7-2, and a two-wire side winding 7-1 is divided into two at the neutral point. Those windings have the same number of turns; the winding 7-1a starts its turn at the neutral-point side terminal and is connected to a DC power source through a capacitor 4, and the winding 7-1b ends its turn at the neutral-point side terminal and is grounded through a capacitor 4. This hybrid transformer 7 serves as the two-wire/four-wire converting circuit and cancels the impedance between both windings to an in-phase noise generated between both lines of the subscriber circuit and the ground, so a feeding detecting circuit 1 is short-circuited to the in-phase noise to evade malfunction.

摘要： PURPOSE:To suppress the oscillation of a circuit by increasing a switching frequency several times higher than the maximum frequency of a transmission/reception signal to prevent a transmission output from leaking to a receiving side. CONSTITUTION:The transmission signal is inputted to a gate of a transmission output transistor FET1, a drain circuit is provided with a series circuit comprising a transmission and reception line T and a switching element FET2, and resistors R1, R2 having a resistance value of several ohms are connected across an FET2. Then, a pulse having a frequency twice or over the transmission signal frequency is applied to a gate of the FET2. Thus, the integrated waveform across the switching element FET2 is similar to that of the transmission signal and they are in-phase to each other then they are cancelled with each other and no transmission signal is leaked to the output side by adjusting the potential to an equal value by a proper method and inputting the result to both input terminals of a differential amplifier OP.
