电压放大倍数是放大电路的一个重要的技术指标。
根据“虚短”和“虚断”的特点,可得到电路的通带电压放大倍数和通带截止频率。
According to "virtual short" and "virtual-off" feature, available to the circuit passband voltage gain and pass-band cut-off frequency.
当频率高于截止频率时,随着频率的升高,电压放大倍数将降低,由此电路具有“低通”的特性。
When the frequency is higher than the cut-off frequency, as the frequency increases, voltage amplification factor will be reduced, thus the circuit has a "low-pass" characteristics.
