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.
