Abstract
A circuit device includes a digital signal processor (DSP) that performs first up-sampling processing of up-sampling up-sampling target data having a first sampling frequency from the first sampling frequency to a second sampling frequency by first interpolation processing, and an arithmetic circuit that performs second up-sampling processing of up-sampling data output from the DSP from the second sampling frequency to a third sampling frequency by second interpolation processing.
