Abstract
Apparatus is provided for generating a self-adjusting saw-tooth wave in response to an input signal containing a plurality of successive start pulses separating time intervals of variable length. The apparatus includes an integrator for generating a ramp signal during each time interval, a comparator for comparing the value of the integrator output signal with a predetermined maximum value and for supplying, at the end of each time interval, the difference therebetween as a correction signal to modify the slope of the ramp signal generated during the next subsequent time interval. The slope of the ramp signal is adjusted to accommodate variations in length of successive time intervals so that the peak value of such ramp signals will equal a predetermined maximum value at the end of successive time intervals of equal length.
