Glossary–7

Unmodulated

  When used to describe television test signals, this term refers to

pulses and pedestals which do not have high-frequency chrominance information
added to them.

V

  The R–Y signal after a weighting factor of 0.877 has been applied.  The

weighting is necessary to reduce peak modulation in the composite signal.

Vectorscope

  A specialized oscilloscope which demodulates the video signal

and presents a display of R–Y versus B–Y in NTSC systems (or V versus U in
PAL systems).  The angle and magnitude of the displayed vectors are respective-
ly related to hue and saturation.

Vertical Interval

  The synchronizing information which appears between fields

and signals the picture monitor to go back to the top of the screen to begin
another vertical scan.

Waveform Monitor

  A specialized oscilloscope that plots voltage versus time

to evaluate television signals.

Y

  Abbreviation for luminance.

Zero Carrier Reference

  A pulse in the vertical interval which is produced by

the demodulator to provide a reference for evaluating depth of modulation.
