PURPOSE: To obtain a digital signal processor which needs not much information amount for generating a sine wave. CONSTITUTION: This processor is provided with a memory 5 being a storage means storing the information for forming a triangular wave, a triangular wave generation circuit 6 to be a triangular wave generation means generating the triangular wave based on the information read out of the memory 5 being the storage means, an amplitude upper and lower limit detection circuit 7 detecting the upper limit and the lower limit of the triangular wave and a band stop filter generating a sine wave by performing a band stop processing for the triangular wave. |
