PROBLEM TO BE SOLVED: To make a frequency modulation apparatus reduced in cost and occupancy space and to execute various kinds of frequency modulation. SOLUTION: A microcomputer chip is utilized to reduce components for modulating a frequency and further to perform arbitrary frequency modulation from low frequency to high frequency and moreover, even when changing contents of frequency modulation, the apparatus is capable of dealing with the change only by rewriting a program of the microcomputer chip.
