Abstract

PURPOSE: To eliminate phase shift to perform a waveform conversion without the generation of a higher harmonic by converting the periodic waveform of a square wave to a sine wave after converting it to a triangular wave.
CONSTITUTION: Data sent from a computer is square wave pulses P1 and P2 of two different frequencies. Pulses P3 and P4 having the half period of input pulses P1 and P2 are obtained. Pulse P3 is converted to triangular wave P5 of peak voltage ev at the same period by an operational amplifier. Meanwhile, P5is inverted by an inverter to obtain triangular wave P6 of bottom voltage ev. Waveforms of outputs F and G obtained by inputting these triangular waves to an analogue switch switched by pulse P1 are synthesized and become pulse P7. Pulse P7 is converted to a sine wave by a limiter circuit. The part of pulse P4 is converted to a sine wave by a similar operation. This sine wave I is proper to be recorded on a magnetic tape, etc.
