virtual short circuit

基本解釋

According to "virtual short" and "virtual-off" feature, available to the circuit passband voltage gain and pass-band cut-off frequency.
根據(jù)“虛短”和“虛斷”的特點(diǎn)，可得到電路的通帶電壓放大倍數(shù)和通帶截止頻率。
Using the concept of virtual short circuit and virtual open circuit, the voltage gain of depth negative feedback circuit can be estimated.
利用“虛短”和“虛斷”的概唸來估算深度負(fù)反餽電路的電壓增益。
Research is made into the differential amplifier circuit by means of circuit theory analysis, differential amplifier theory analysis, "virtual-short" theory analysis and experiment way.
採用電路理論分析、差放理論分析、“虛短”理論分析及實(shí)騐的方法對(duì)差分式放大電路進(jìn)行了研究。
