Preliminary Clipping a Waveform
Clipping a Waveform
Digitally modulated signals with high power peaks can cause intermodulation distortion, resulting in
spectral regrowth that can interfere with signals in adjacent frequency bands. The clipping function
enables you to reduce high power peaks by clipping the I and Q data to a selected percentage of its
highest peak, thereby reducing spectral regrowth.
