Answer: c
Explanation: A phase lag lead network is the network that is similar to the differentiator and it is used to increase the speed response and increases the stability of the system and this introduces lag at low frequencies and lead at high frequencies.

A phase lag-lead network is a type of electronic circuit that is used to introduce a specific phase shift in the output signal with respect to the input signal. This phase shift can be either a lag or a lead, depending on the frequency of the input signal. In the case of a phase lag-lead network, the output exhibits a lag at low frequencies and a lead at high frequencies.
Explanation:
- Phase Lag: In a phase lag network, the output signal lags behind the input signal. This means that the output waveform reaches its peak or crosses the zero axis after the input waveform. The amount of lag is determined by the frequency of the input signal. At low frequencies, the lag is more prominent.
- Phase Lead: In a phase lead network, the output signal leads the input signal. This means that the output waveform reaches its peak or crosses the zero axis before the input waveform. The amount of lead is determined by the frequency of the input signal. At high frequencies, the lead is more prominent.
In the case of a phase lag-lead network:
- At low frequencies, the network introduces a phase lag in the output signal. This means that the output waveform lags behind the input waveform.
- At high frequencies, the network introduces a phase lead in the output signal. This means that the output waveform leads the input waveform.
Hence, the correct answer is option 'C' - "Lag at low frequencies and lead at high frequencies".
This behavior of a phase lag-lead network is useful in many applications. For example, in control systems, it can be used to stabilize the system and improve its response by compensating for phase delays or leads introduced by other components. It can also be used in audio systems to correct for frequency-dependent phase shifts and improve the overall sound quality.
