Pulse Distortion

Ideally the output pulse waveform should be identical in shape to the input pulse waveform except for a desired amplitude change due to the “step-up” or “step-down” turns ratio. Any other deviation is considered to be distortion. Rise time, droop, trailing edges, and spurious oscillations are all considered to be signal distortions.

Figure 3B illustrates all of these distortions.
