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.
