    Active High Pass Filter - Op-amp High Pass Filter

    Then, the Active High Pass Filter has a gain A F that increases from 0Hz to the low frequency cut-off point, ƒ C at 20dB/decade as the frequency increases. At ƒ C the gain is 0.707*A F, and after ƒ C all frequencies are pass band frequencies so the filter has a constant gain A F with the highest frequency being determined by the closed loop bandwidth of the op-amp. As with low-pass filters, high-pass filters have a rated cutoff frequency, above which the output voltage increases above 70.7% of the input voltage. Just as in the case of the capacitive low-pass filter circuit, the capacitive high-pass filter’s cutoff frequency can be found with the same formula: Thorlabs' Passive Electrical Filters are feedthrough BNC filters that allow the user to filter unwanted signals and noise with a guaranteed minimum rejection of 40 dB.
