Answer
Noise interference arises when external thermal or electromagnetic sources create unwanted signals within the circuit. This can result in the degradation of the main signal, thereby reducing the performance of the circuit.

Answer
Cross-talk interference occurs when signal paths accidentally couple with each other, leading to unwanted transmission of signals. This can result in corruption of the intended signal and potential data loss.

Answer
Impedance mismatch interference takes place when there is a discrepancy between the load impedance and the source impedance. This can lead to signal reflections, resulting in a loss of power and degradation of the signal integrity.
