Abstract : The article analyzes the operation of a single-track telephone repeater with a single amplifier which is alternately switched on in either direction, i.e., in whichever direction the voice-carrying current flows. A block diagram of the system, the waveform of the voltages involved in the process of transmission are considered here; load matching conditions are derived on the basis of equivalent circuit parameters and, furthermore, amplitude- as well as phase-distortions in the amplifier circuit are discussed.
