Abstract
A processing-efficient chirp generator that allows flexibility in controlling phase, frequency and slope, i.e., rate of change of frequency. In one embodiment, a fine phase propagation block generates phase values in increments of the fine time step, each phase value also offset from other phase values by multiples of a coarse time step. The phase samples are realigned in time after conversion to digital-to-analog converter (DAC) values.
