Negative feedback is a technique used in electronic circuits to reduce distortion and improve the bandwidth of the system. It involves feeding back a portion of the output signal to the input, but with opposite polarity. This feedback signal is then subtracted from the input signal, resulting in a reduced error signal.
Negative feedback has several effects on the distortion and bandwidth of a system. Let's discuss each of them in detail:
1. Distortion reduction:
- Negative feedback helps in reducing distortion in the system by minimizing the effect of nonlinearities present in the circuit components.
- Nonlinearities in electronic components can introduce harmonics and intermodulation distortion, which can degrade the quality of the output signal.
- By applying negative feedback, the nonlinearity of the components is compensated, resulting in a more linear response.
- The feedback signal is designed to counteract the nonlinearities, thus reducing the overall distortion.
2. Bandwidth improvement:
- Negative feedback also improves the bandwidth of the system by reducing the effects of parasitic capacitance and inductance.
- Parasitic capacitance and inductance can limit the high-frequency response of a circuit, leading to a reduced bandwidth.
- By applying negative feedback, the feedback signal is coupled to the input, effectively bypassing the parasitic elements.
- This bypassing reduces the effect of parasitic elements on the overall response of the circuit, thereby increasing the bandwidth.
In summary, negative feedback reduces distortion by compensating for nonlinearities in the system and improves the bandwidth by bypassing the effects of parasitic capacitance and inductance. Hence, option 'C' is the correct answer.
