In
broadcast television systems, VF bandwidth, video bandwidth or more formally video frequency
bandwidth is the range of frequencies between 0 and the highest
frequency used to transmit a
live television image. The maximum frequency can be found by multiplying three figures; the number of
frames
A frame is often a structural system that supports other components of a physical construction and/or steel frame that limits the construction's extent.
Frame and FRAME may also refer to:
Physical objects
In building construction

sine
In mathematics, sine and cosine are trigonometric functions of an angle. The sine and cosine of an acute angle are defined in the context of a right triangle: for the specified angle, its sine is the ratio of the length of the side that is oppo ...
periods per line. In the table below number of frames per second, number of lines per frame and the video band width in different systems are shown.
