A system includes a storage device containing machine instructions and a plurality of digital values of an oversampled sinuisoidal signal. The system also includes a core coupled to the storage. The core is configured to execute the machine instructions, wherein, when executed, the machine instructions cause the core to implement a sigma-delta modulator that retrieves the plurality of digital values from the storage device as input to the modulator. The sigma-delta modulator is configured compute an output bit stream. The system further includes an analog filter configured to receive the output bit stream from the core and to low-pass filter the output bit stream to produce a sinusoidal output signal.
