A signal Vmsin (ωt + φ) is applied to an amplifier whose gain A is independent of frequency. The amplifier will preserve the form of the input signal (though with a delay) if the phase shift φ is:

• Phase shift in an amplifier is the amount (if any) by which the output signal is delayed or advanced in phase with respect to the input signal expressed in degrees.
• Such a shift can be caused by the effect of correspondents such as resistors, inductors, and capacitors in the amplifier circuit.
• The phase management in analogy circuits normally targets phase linearity with frequency.
• Since if the phase is linear with frequency, there will be no phase distortion and the group delay time will be constantly leading to preservation of the waveforms
• Even if analog circuits do not have phase-frequency linearity one can use phase equalizers to linearizer the phase.
