Abstract
An apparatus for generating an output signal having a waveform that is repeated every period, includes a storage configured to store values corresponding to the waveform in a portion of a period of the output signal, a counter configured to generate a first index of a sample included in the output signal, a controller configured to generate at least one control signal based on the first index and the period of the output signal, and a calculation circuit configured to generate the output signal by calculating an output from the storage based on the at least one control signal.
