Figure 6-19. Oscilloscope Display of the WINDOW, Signal Waveform, Black Polarity
NOTE
V Stripe
The horizontal component of the window signal presented for the full duration of
the vertical television field will develop a vertical stripe on the televised display.
This will provide an approximate 50% duty cycle (APL),thus preventing the
development of distortion which may be present during the lower APL of the
window signal. Therefore the transient response and midfrequency response can
be evaluated without distortion due to low frequency defects.
