DEFINITION

Classification: 348/912

DIFFERENTIAL AMPLITUDE CONSIDERATION (E.G., AMPLITUDE VS. FREQUENCY):

Art collection of television circuits correcting for distortions resulting from the system, wherein the distortion occurs when the amplitude at different frequencies over the frequency range required for transmission is not constant.

(1) Note. Normally the higher frequencies have a lower amplitude than the lower frequencies which is often referred to as roll-off; these circuits normally give greater amplification to the higher frequencies to compensate for the "roll-off" caused by the system.
