Abstract
Disclosed is a digital circuit for generating a swept clock frequency having a linear rate of change. A constant frequency signal is divided by a counter signal representative of the inverse of a linearly changing time dependent variable. The value of the counter signal is varied at the proper rate by means of a pair of rate multipliers and a frequency divider. Included are means for controlling the slope of the output frequency.
