PLLs are useful in a variety of applications, most notably cable and TV tuners. In these systems, the PLL synchronizes an output signal (typically from a VCO) with a reference or input signal, in frequency as well as in phase. The VCO in these PLLs requires a biasing circuit.
It can be placed in any place in the path of the video signal. The VITS generator is configurable. Lines can cross the VITS generator without modification, others are erased and recreated in the VITS generator.
This simple adapter can be used to convert Y/C video (S-video) to a composite video. This adapter is useful in cases where your video output device has only S-video output but your signal source accepts only composite video input. This circuit works with both PAL and NTSC video standards.
Build a miniature short-range wireless video system with off-the-shelf parts. The video modulator provides a simple method for interfacing the video signal to a standard TV. Transmission distance is limited to a few feet.
converts the analog RGB video signal that is output by the ST to an NTSC composite signal which can be displayed on a colour or monochrome composite monitor, or on a TV set by adding a modulator.
This filter is a 0.1 dB Tschebychev lowpass with a rejection of 90 dB or better at 430 MHz, and 0.2 dB insertion loss at 72 MHz. The 3 dB cutoff frequency is 120 MHz.
