Filed: 1987-06-11
Abstract: PURPOSE:To miniaturize and simplify a circuit structure regardless of the number of phases by generating a wave which is phase-modulated according to sent data by using a digital signal obtained by adding sum data based upon the sent data to a counted value of clock pulses. CONSTITUTION:A counter 6 counts clock pulses from a pulse generator 1 and inputs a three-bit sequential binary signal to an adder 7. The adder 7 adds the input binary sequential signal to sum data D1 and D2 inputted from a sum data input terminal 70 and inputs the addition result to a converter 8. The converter 8 converts the sequential binary signal into an artificial sine wave and inputs it to a band-pass filter 5, which reduces its unnecessary frequency components to perform waveform shaping processing so that the wave approximates to a real sine wave. Therefore, the need for a circuit which generates carriers by the phases and an output switching part for the circuit is eliminated, and the circuit constitution is reduced in size and simplified.
