  • Saw television scrambling system
    Patent number: 6081599
    Abstract: A television scrambling system in which a television signal is scrambled by means of placing a scrambling (or jamming) signal into the luminance signal spectrum on the transmit side. On the receive side, the jamming signal is removed by a Surface Acoustic Wave (SAW) notch filter. On the transmit side, pre-correction of the television signal is performed to compensate for amplitude and phase distortions introduced by the SAW notch filter.
