Horizontal Frequency
The time required to scan a single line
from the left to the right side of the
screen is called a horizontal cycle. The
reciprocal number of a horizontal cycle
is called horizontal frequency. Horizontal
frequency is measured in kHz.
-
Vertical Frequency
Repeating the same picture dozens of
times per second allows you to view
natural pictures. The repeat frequency is
called "vertical frequency" or "refresh rate"
and is indicated in Hz.
