How does negative feedback help in reducing distortion in amplifiers?

• Negative feedback increases distortion by amplifying the input signal

• Negative feedback corrects the output signal based on the input signal.

• Negative feedback has no effect on reducing distortion in amplifiers

• Negative feedback causes the output signal to deviate further from the input signal

Explain how negative feedback improves the stability of amplifiers.

• Negative feedback has no effect on the stability of amplifiers.

• Negative feedback causes the amplifier to produce distorted output, reducing stability.

• Negative feedback increases the gain of the amplifier, making it more sensitive to variations in components and temperature, thus decreasing stability.

• Negative feedback reduces the gain of the amplifier, making it less sensitive to variations in components and temperature, thus improving stability.

What role does negative feedback play in reducing noise in amplifiers?

• Negative feedback has no effect on reducing noise in amplifiers.

• Negative feedback increases noise by amplifying the gain of the amplifier at higher frequencies.

• Negative feedback reduces noise by reducing the gain of the amplifier at higher frequencies.

• Negative feedback reduces noise by increasing the gain of the amplifier at higher frequencies.
