Abstract

A discrete coherent chirp generator capable of generating a plurality of coherent sinusoidal signals. The chirp generator comprises a programmable read only memory containing samples of one period of a sine wave. Additional circuitry generates addresses to the programmable read only memory at periodic intervals to cause samples of a sine wave of the desired frequency to be read out of the programmable read only memory. As a particular application, a plurality of frequency modulated signals can also be generated.
