Abstract
A pulse generator with adjustable pulse frequency, pulse width and pulse delay contains a start-stop oscillator (1) whose oscillator pulses are counted by a counter (2) in adjustable counting cycles. After each counting cycle, the oscillator (1) is shut down for an adjustable time interval. The pulses of the output signal of the pulse generator are produced at the occurrence of a predetermined count value, and the end of these pulses is essentially determined by a second predetermined count value. As the oscillator (1) has a fixed operating frequency and for the purpose of frequency interpolation is periodically shut down during short time intervals and then restarted, a pulse generator is obtained having very small frequency deviations over a wide frequency spectrum.
