SIGNAL GENERATION DEVICE AND SIGNAL GENERATION METHOD

摘要

Provided with filter banks (2-0 to 2-(L-1)) that perform sampling frequency conversion on an input signal with a prescribed sampling frequency and generate a post-sampling frequency conversion signal as an output signal, and a control signal generation unit (3) that selects the filter banks (2-0 to 2-(L-1)) used on the basis of a sampling frequency setting that indicates the sampling frequency of the output signal. A switching unit (4) selects the filter banks (2-0 to 2-(L-1)) on the basis of the selection results from the control signal generation unit (3).
