is required to handle a large swing of voltage and current.
Due to presence of harmonics in output signal, the output voltage waveform will be distorted. This is called harmonic distortion
. Usually, the type of distortion is analysed using Fourier series.
Second Harmonic Distortion
The parabolic equation and the output voltage is different from input voltage and output is distorted in nature. This distortion is called nonlinear distortion
or amplitude distortion
The difference between the input signal waveform and output signal waveform in an amplifier is called distortion
