Abstract
PURPOSE:To enable sine wave signal generation having small higher harmonic distortion with a simple constitution by two-frequency-dividing and adding a rectangular wave signal with the frequency-divider of a serial connection successively, after a triangular wave signal is composed, removing a higher harmonic wave and generating a sine wave signal. CONSTITUTION:The rectangular wave signal of a prescribed frequency is successively two-frequency-divided by 1/2-frequency-dividers 2-5 of a serial connection. The output of the frequency-divider 5 through a gate circuit 6, respective outputs of respective frequency-dividers 2-4 and the inversion output are added by an adder 7 and an approximately triangular shaped triangular wave signal is composed. The triangular wave signal is processed by an LPF 9, a higher harmonic component is removed and a sine wave signal is generated. By a constitution using the triangular wave signal having a small quantity of the higher harmonic wave, sine wave signal having a higher-harmonic distortion can be generated from a rectangular wave signal with a simple constitution.
