WORKING/STANDBY CLOCK PULSE SUPPLY FOR DIGITAL SYSTEMS

摘要

A working/standby clock pulse supply for digital systems, particularly for synchronous multiplex systems and switching systems, has a working clock oscillator and a standby oscillator. The working clock signal or the standby clock signal is guided by way of assemblies whereby at least one clock signal summing circuit is provided which adds equal harmonic spectral signals of various amplitudes of the working clock signal and the standby clock signal to provide a resulting spectral signal.
