Abstract
A signal processing circuit comprising a clip-generation-block. The clip-generation-block is configured to receive an input-signal; and determine a clip-signal that comprises only values of the input-signal that exceed a clipping-threshold. The signal processing circuit also comprises a scaling-block configured to apply a scaling-factor to the clip-signal in order to generate a scaled-clip-signal, wherein the scaling-factor is greater than one; and an adder configured to provide a clipped-signal based on a difference between the scaled-clip-signal and the input signal.
Claims15
A signal processing circuit comprising:
- a clip-generation-block configured to:
- receive an input-signal;
- and
- determine a clip-signal that comprises only values of the input-signal that exceed a clipping-threshold;
- a scaling-block configured to apply a scaling-factor to the clip-signal in order to generate a scaled-clip-signal, wherein the scaling-factor is greater than one;
- and
- an adder configured to provide a clipped-signal based on a difference between the scaled-clip-signal and the input signal.
A method of processing an input-signal, the method comprising:
- determining a clip-signal that comprises only values of the input-signal that exceed a clipping-threshold;
- applying a scaling-factor to the clip-signal in order to generate a scaled-clip-signal, wherein the scaling-factor is greater than one;
- and
- providing a clipped-signal based on a difference between the scaled-clip-signal and the input signal.
