Negative feedback in an amplifier has several effects:

1. Improves the signal-to-noise ratio at output: Negative feedback helps to suppress the noise generated within the amplifier, thus improving the signal-to-noise ratio at the output.

2. Reduces Distortion: Negative feedback can significantly reduce the distortion caused by the non-linear characteristics of the elements within the amplifier.

3. Improves the signal-to-noise ratio at input: By reducing the gain of the amplifier, negative feedback can also improve the signal-to-noise ratio at the input.

4. Does not improve the signal-to-noise ratio at I/O: This statement is not entirely correct. While it's true that negative feedback does not directly improve the signal-to-noise ratio at the input/output (I/O), it does indirectly improve it by reducing distortion and noise within the amplifier.
