Passive Low Pass Filter
As the filter contains a capacitor, the Phase Angle ( Φ) of the output signal LAGS behind that of the input and at the -3dB cut-off frequency ( ƒc) is -45 o out of phase. This is due to the time taken to charge the plates of the capacitor as the input voltage changes, resulting in the output voltage (the voltage across the capacitor) "lagging" behind that of the input signal.
