| Abstract: | The method of generating various kinds of complicated process signals by using sound card and through VB programming to modify WAV files is introduced. The practice shows that this signal generator is valuable in generating some complicated signals in process control with low frequency, e.g., signal of Vortex flowmeter, etc. |
