WebJun 30, 2016 · If you consider an ideal low-pass filter with cut-off frequency of f c, all frequencies greater than f c will be removed. Then it's bandwidth is equal to f c H z (from 0 up to f c ). The total bandwidth B T is simply twice that: B T = 2 f c, since we are also considering negative frequencies, from − f c up to f c. Here is a picture of that ... WebIn an RL low pass, the output voltage lags behind the input voltage by 0 ° to -90 °, depending on the frequency. At the resonance frequency, the phase shift is -45 °. At low frequencies it tends towards 0. At high frequencies the phase rotates towards -90 °. The phase shift can be calculated using the following formula.
