A Constant Amplitude Variable Frequency Synchronized Linear Ramp Generator.
Abstract
A constant amplitude, variable frequency, synchronizied, linear ramp generator is disclosed for generating a sawtooth waveform signal, whose amplitude is independent of frequency. A capacitor is charged by a voltage controlled current source, which is responsive to a feedback control signal provided by an integrator; and subsequently discharged by a clamp, which is responsive to a trigger pulse signal, so as to establish a ramp voltage across the capacitor. The ramp voltage, which appears at the output of the linear ramp generator as the sawtooth waveform signal, in turn allows a television system to operate at various line rates. (Author)
