Abstract

PURPOSE:To obtain the signal in frequency multiplex with good efficiency, by obtaining the multiplexed output through the supply of input signal opposite in phase each other to a pair of inputs of the differential amplifier and multiplying this output with one output of the differential amplifier. CONSTITUTION:The input signal (a) is fed to the operational amlifier 4 from the input terminal 3 to obtain the signals (a) and (a') of opposite polarity each other. The both signals (a), (a') are fed to the differential amplifier 6 in common emitter connection of a pair of transistors T1 and T2. Further, the multiplexed output of the input signal obtained from the common connection emitter is compared with the reference level to obtain the output (c), in which the period of the multiplex output is divided into 1/n. This divided output (c) and the one output (b) of the differential amplifier 6 are multiplied 8 to obtain the signal in frequency multiplex of the input signal.
