Abstract
A pre-emphasis network used in a television signal jamming encoder has a variable gain tuned amplifier first stage and an attenuable notch filter and variable gain broadband amplifier second stage. The notch filter is tuned to a center frequency above the television signal intermediate frequency's visual carrier frequency resulting in 15 dB of increased pre-emphasis and a time delay which compensates for a time delay imparted by a decoding network upon decoding of a signal jammed by this encoder.
