Fortunately, this signal is much higher than the critical frequency, but may cause some problems for low-noise applications. Another problem arises from the fact that switched capacitor filters are actually sampled data … 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. jonesing around
