Abstract
A device includes a plurality of phase accumulators, a multiplexer, and an oscillator. The plurality of phase accumulators is configured to receive a plurality of frequencies and generate a plurality of ramp signals. The multiplexer is configured to receive the plurality of ramp signals from the plurality of phase accumulators and to select one ramp signal from the plurality of ramp signals. The oscillator is configured to receive the one selected ramp signal and to generate one amplitude signal associated therewith. The plurality of phase accumulators continues generating their respective ramp signal. The multiplexer subsequent to selecting the one ramp signal is configured to select another ramp signal associated with another one phase accumulator of the plurality of phase accumulators. The oscillator is further configured to receive the selected another ramp signal and to generate another amplitude signal associated therewith.
