Figure 22 and Figure 23, the top line illustrates the
full signal and the bottom line is a more detailed view
of the last three sine wave bursts.

check for pulse distortion and reflection, and the 20T
pulse is used to check for amplitude and group delay
between chrominance and luminance. Neither pulse
exhibits any distortion or group delay artifacts.
