电路如附图所示。在开关S1置于“1”时,再按下按钮S2后则产生单脉冲,在释放时,脉冲将衰减下去;在S1置于“2”时,则可产生1～25Hz频率范围内的可调连续脉冲。
Circuit shown in the figure. When switch S1 is set to “1” and then button S2 is pressed, a single pulse will be generated and the pulse will decay when it is released. When S1 is set to “2”, it can generate frequency range of 1 ~ 25Hz Adjust continuous pulse.
