Abstract
PURPOSE:To obtain a comparatively simple circuit, capable of converting a binary signal into a quaternary signal and transmitting it by providing a series parallel converting part, an operational amplification circuit and a transmitting part. CONSTITUTION:Two bits of the binary signal are made into one symbol by the series parallel converting part 1, and in the operational amplification circuit 2, when the signal of one side converted into a parallel signal, is 1 and 0, it is considered to be, for instance, a positive polarity signal and a negative polarity signal respectively, and when the signal of the other side is 1 and 0, it is considered to be the signal of 3 level and 1 level respectively. Then, these are synthesized, and when the two bits of the binary signal is 11, it is considered to be the quaternary signal of +3 level, and when 10, 01, and 00, it is considered to be the quaternary signal of +1 level, -1 level and -3 level respectively, and the quaternary signal is transmitted from the transmitting part 3 to a transmission line. Thus, the binary signal can be converted into the quaternary signal and can be transmitted by the simple constitution of the series parallel converting part 1 and the operational amplification circuit 2.
