ABSTRACT:
This disclosure relates to a fail-safe constant amplitude signal generator including a shunt regulator for supplying d.c. operating potential to a free-running transistor oscillator as well as for controlling the quality factor of a resonant tuned circuit and, in turn, the oscillator so that an a.c. output signal is capable of being produced with a known amplitude which cannot be changed by any critical circuit or component failure.
