有两种类型串联RC电路。要分析的第一种是低通电路(low-passfilter),和在相位滞后电路中一样,它是通过从电容上取输出信号来实现的。第二种是高通电路(high-pass fil-ter),和在相位超前电路中一样,它是通过从电阻上取输出信号来实现的。在实际中,RC电路都是与运算放大器一起使用构成一个有源滤波器,它比无源RC...
Filters can be placed into broad categories that correspond to the general characteristics of the filter’sfrequency response. If a filter passes low frequencies and blocks high frequencies, it is called a low-pass filter. If it blocks low frequencies and passes high frequencies, it is a...

NAME DATE Project 2-2 RC Active Filter Design and Testing 1 Objective Design, build, and test an RC active band-pass filter. Introduction For audio and below 1-MHz applications, LC filters are no longer widely used because of the high cost, ...
The simple CRL snubber is a low pass filter attenuating frequencies above its natural resonance. A steady state sinusoidal input voltage results in a sine wave output at the same frequency. With no snubber resistor, the rate of roll off approaches 12 dB per octave. The corner frequency is at...

I am trying to learn PLECS. I have a simple RC low pass filter I want to measure the frequency response. Please see the attachment. I can not connect the AC source to the resistor. The system doe snot allow it. I t…
The capacitor Cin at the input acts as a filter which is used to block the DC voltage and allow only AC voltage to the transistor. If any external DC voltage reaches the base of the transistor, it will alter the biasing conditions and affects the performance of the amplifier. ...
For maximum protection, the current flow through the resistor RS should be low, but as stated above, this might increase the possibility of momentary interference with the load operation. Thus, the value of the resistance RS is determined based upon a trade off between protection in a multi-lo...
