A non-linear circuit is one in which the output is not directly proportional to the input, often resulting in complex behaviors such as harmonics and signal distortion. These circuits are essential in applications like amplifiers and oscillators, where non-linear characteristics are exploited to achieve desired signal processing effects.

Output is not directly proportional to the input

Complex Behaviors

Harmonics are integral multiples of a fundamental frequency, adding richness and complexity to sound waves and electrical signals. They are crucial in fields like music, acoustics, and electrical engineering for analyzing waveforms and ensuring system efficiency.

Harmonics

Signal distortion refers to any alteration of a signal's original waveform or other characteristics as it travels through a transmission medium. It can degrade the quality of the signal, leading to errors in data transmission and reduced communication efficiency.
