    • PURPOSE:To realize a testing method for a tone signal generation circuit capable of efficiently testing a tone signal by collating the compression data for which plural tone signals are compressed with correct solution data in the testing method for the tone signal generation circuit of an electronic exchange. CONSTITUTION:This testing method for tone signal generation circuit is provided with a compression means 10 compressing the digital tone signal generated by a tone signal generation circuit 1 on a tone highway only by prescribed time, a control means 20 generating a control signal controlling the reset, the the start and stop of the operation of the tone signal generation circuit 1 and a comparison means 30 comparing the data for which a tone signal is compressed by a compression means 10 with an expected value when a normal digital tone signal is compressed for the prescribed time. By comparing the data for which tone signal generated by the tone signal generation circuit 1 is compressed by a compression means 10 only for prescribed time with the expected value when the normal digital tone signal is compressed for prescribed time by the comparison means 30, the tone signal generation circuit 1 is tested.
