ABSTRACT:
Methods for operating a control circuit, having a programmable signal characteristic, in a manner so as to gradually vary a D.C. analog output level from an initial value to a final value, as well as for abrupt changes therein, when an isolation-and-rectification network is used to recover a D.C. voltage of programmably controlled amplitude. The methods also provide for a pulsed output condition in a circuit for providing a periodic signal of programmably controlled amplitude. In such a circuit, the output signal amplitude may be controlled by external data signals to values less than, equal to and greater than, the substantially constant amplitude of an oscillator waveform. Both programmable (computer-controlled) and hard-wired circuitry are disclosed for controlling the output signal by the methods of this invention.
