Abstract

PURPOSE: To obtain a synthetic wave between a periodical vibration wave of a prescribed period and a periodical vibration wave of a period of the 1/(an integral) of the wave above by scanning n-number voltage generation circuits with p-number scanning signals.
CONSTITUTION: By turning on transistor 51 of scanning switches F1∼F32 by voltages V1∼V4 of voltage generation circuits A1∼A4 and scanning signals Q1∼Q32 having a width of period T0, which is, for example, 32 times as long as pulse train PC of fixed period τ0 from scanning signal generation circuit 12, peridical vibration wave voltages V01∼V04 having periods T0, T0/2∼T0/4 respectively are obtained at non- non-inversion input terminal 41 of differential amplifier 45 of operational amplifier circuit 21. Consequently, a periodical vibration wave of period T0 where voltages V01∼V04 are synthesized can be obtained at terminal 46.
