I am trying to calculate the Thevenin equivalent circuit of this low pass filter however, I have never done it with an AC input and am getting very confused. R=100Ω;C=2μFR=100Ω;C=2μF Vin=2sin(2π∗40∗t)+3sin(2π∗142∗t)+sin(2π∗400∗t)Vin=2sin(2π...
The frequency cutoff point is the point in the circuit in which there is a 3dB drop in amplitude. A 3dB drop equals 0.707VPEAK. If you look at the low pass filter graph shown above, there is a peak amplitude, VPEAK. Then as you get to the , the amplitude drops. When it reaches 0....
