Abstract

PURPOSE:To make a filter circuit simple and compact, by modulating reference sinusoidal waves by high-frequency waves, changing the modulated signal back into the sinusoidal waves as an AC output and applying a portion of the output to an addition circuit through a circuit for comparison with set sinusoidal waves. CONSTITUTION:A clock signal of an oscillation circuit 1 is frequency-divided by a frequency division circuit 2, the output of which is applied to a sinusoidal wave generation circuit 3. The sinusoidal output of the circuit 3 is applied to the addition circuit 4 together with the signal which is produced by supplying a portion of an output to a circuit 13 for comparison with set sinusoidal waves 12. The output of the addition circuit is applied to a comparator 6 together with a triangular output of a triangular wave generation circuit 8 to perform pulse width modulation. The output of the comparator is separated by a signal separation circuit 7. A separated signal is entered into a DC/AC conversion circuit 9. A DC input 10 is changed into a sinusoidal AC output. Since the modulation is effected by high-frequency waves, the cut-off frequency of a filter can be set high and it can be made compact.
