Abstract

The frequency multiplier has slow and rapid frequency generators, the rapid generator giving a frequency 360 times the frequency of the slow generator. Each input pulse returns to zero the two generators. A chosen parameter of the rapid generator returns this generator to zero each time this chosen parameter reaches the value corresponding to the same chosen parameter of the slow generator at the moment of arrival of the preceding input pulse. The zero resetting of the rapid generator supplies frequency output pulses 360 times the frequency of the input pulses.
