Abstract
A frequency transmission system comprises a pulse train generator and a signal converter. The pulse train generator generates a pulse signal of a sufficiently short duration in response to oscillation frequency signals, and the signal converter circuit converts the pulse signal into a current signal and blunts the waveform of the converted signal by a capacitor to transmit through power supply lines.
