利用Multisim仿真软件通过改变积分电路与电容的并联电阻和输入电阻的比值，得到其与输出信号的波形情况和输出信号的幅度之间的关系。比值越大输出信号的幅度越大。电路的工作状态由输入信号的频率、积分电路电容以及并联电阻决定，当输入信号的频率大于或者等于10倍的半功率点频率时为积分运算电路。
利用Multisim倣真軟件通過改變積分電路與電容的併聯電阻和輸入電阻的比值，得到其與輸齣信號的波形情況和輸齣信號的幅度之間的關繫。比值越大輸齣信號的幅度越大。電路的工作狀態由輸入信號的頻率、積分電路電容以及併聯電阻決定，噹輸入信號的頻率大于或者等于10倍的半功率點頻率時為積分運算電路。

By using of Multisim simulation software and changing the ratio of the shunt resistor with the capacitance and the in-put resistor in the integrating circuit, the author obtain the relationship between the that ratio and the case of the output signal waveforms, as well as the relationship between the that ratio and the amplitude of the output signal.The greater that ratio is, the greater the output signal amplitude is.The working state of the circuit is determined by the input signal frequency and the capacitance of the integrating circuit and parallel resistance.When he frequency of the input signal is greater than or equal to 10 times the half-power point,the arithmetic circuit is the integral circuit.
