Clipping Power Amplifier

Model of a power amplifier driven into saturation. Complex signal samples with amplitudes above \(s_\mathrm{sat} \in \mathbb{R}\) will be clipped to the maximum amplitude value. In case of clipping, the respective sample angles will be preserved, so that

\[s'(t) = \frac{s(t)}{|s(t)|} \cdot \min{(|s(t)|, s_\mathrm{sat})} \text{.}\]
