| Abstract: | The distortion is one of the ehmacters of the signal. A new design of distortion test instrument based on MCU is descrihed in this paper, whieh using the method of fundamental wave elimination, can control the resonance fi＇equency and achieve the test of sound signal, and then display the test resahs. The design is cheap and applied, the test resuh indicates that this instrument is reliahle and accurate. |
