ELECTRONIC SOUND SOURCE HAVING REDUCED SPURIOUS EMISSIONS

摘要

An electronic sound source comprises an adder which calculates a sum of volume data and differential volume data in response to each dock signal supplied at equal intervals of time and transfers it to a limiter and a volume register. The sum volume data is then limited to a predetermined value by the limiter and passed across a volume register to a volume controller where it is multiplied by an output of a mute processor.
