Digital sinewave reference generator
A low-cost microcontroller drives a D/A converter, whose output signal is filtered using a bandpass in order to suppress alias frequencies. This setup guarantees an output signal that’s spectrally pure as well as stable in respect of amplitude and frequency — everything you would like to have for spot-frequency measurements.
