Abstract
An apparatus and method for providing distortion to an input signal. A first alternating current component is separated from the input signal, to provide a first signal representing the first alternating current component and a second signal representing the input signal having the first alternating current component separated therefrom. The signal level of the first and second signals is adjusted. Nonlinear distortion is provided to the signal level adjusted first signal, to produce a distorted first signal. The signal level adjusted second signal is combined with the distorted first signal, to produce a corresponding output signal.
