3.8 Clipper

The Clipper, shown below in Figure 3-18, can be used to achieve digitally the specified THD levels without voltage clipping. It allows users to achieve the same THD (for example, 10% THD) for different power levels (15W, 10W, 5W) with same PVCC level.

    Clipper Leve (dB) The Clipper Level controls the signal level at which clipping occurs.
    Makeup Gain (dB) The Makeup Gain sets additional gain steps from –110dB to 6dB.
