Abstract
An improved ramp generator system includes a plurality of ramp generator circuits; a ramp rate signal source for controlling the ramp slope; a ramp voltage signal source for establishing the starting voltage of the ramp; a ramp starting signal source for starting the ramp; a device for defining a plurality of ramp periods; and a switching device, responsive to the device for defining the ramp periods, for alternately, sequentially connecting the ramp rate signal source, ramp voltage signal source, and ramp starting signal source, to each of the ramp generator circuits for producing a series of identical ramps.
