| Abstract: | Stress wave time instrument mainly includes: accelerometer, pulse converter, counter, decode and display unit. It can measure the time that stress wave pass through the material. So the travelling speed of stress wave can be obtained. In this paper, the design method of signal amplifier, gate signal producing and counter circuit was presented. |
