Abstract
Retrace pulses are integrated by an R-C network to produce a ramp signal. The resistive member of the R-C network is bypassed by a diode to provide rapid retrace at the conclusion of the ramp portion of the integrated signal. A voltage divider at the output of the integrator adjusts the DC level of the ramp signal without affecting the constant of integration of the R-C network.
