Active High Pass Filter Circuit Design and Applications
Voltage Gain Of an Active High Pass Filter. Voltage Gain A v = A max (f/f c) / √{1 + (f/fc)²}. Wheref = operating frequency. fc = cut-off frequency. A max = pass band gain of the filter = 1 + (R 3 /R 2). At low frequencies i.e. when the operating frequency is less than the cut-off frequency, the voltage gain is less than the pass band gain A max.At high …
Why are high values of capacitance in low pass active filters not ...
High value capacitors have lower leakage resistance associated with them. Certainly this depends on the type of capacitor used. If you use paper/mica capacitors their leakage is relatively lesser but they are often too bulky. So if you want to generate 1 Hz, it is not difficult, but generating 0.001 Hz will be.
