Hard Clipping

A widespread class of distortion used in electric guitars, is clipping of the guitar waveform. it is easy to add this effect to any string-simulation algorithm by passing the output signal through a nonlinear clipping function. For example, a hard clipper has the characteristic (in normalized form)

$\displaystyle f(x) = \left\{\begin{array}{ll} -1, & x\leq -1 \\ [5pt] x, & -1 \leq x \leq 1 \\ [5pt] 1, & x\geq 1 \\ \end{array} \right. \protect$ (10.4)

where $ x$ denotes the current input sample $ x(n)$, and $ f(x)$ denotes the output of the nonlinearity.
