Circuits to transmit & Demoludate RF / video signals over fibre optic cable - There exist possibilities to transfer an RF signal into a Fibre Optic cable or Dielectric waveguide. There are ways that this can be achieved by using digital or analogue methods. The simplest way is by using analogue modulation. This can done by using AM (Amplitude Modulation) or FM (Frequency Modulation) techniques. __ Designed by Andrew Quinn

Color Video Travels On Twisted-Pair Cable - 08/17/95 EDN Design Ideas: This circuit transmits video anywhere phone lines exist. Although the circuit has more electronic components than the traditional single amplifier used to drive a coax cable, you can easily justify the additional electronics required to drive twisted-pair cables Design by Raphael Horton, National Semiconductor, Santa Clara, CA
Colour Bar Generator - I started this project 3 weeks ago, because I was wondering " is that possible, some AVR MCU to create simple colour bars? " At the beginning, I believed that it's easy. So, I asked some people who knew more about PAL composite video signal. The first idea was to work with 8.867238 MHz crystal (2 times the color carrier). When I read about PAL video composite signal creation, I saw that if you want to product colors entire-in-software you must create the color-carrier (4.43 MHz) , changing 4 times the phase of color-carrier (one time for each color) , to show 4 colours. Except that, you have to change the color-burst from 135 deg to 135+90= 225 deg. __ Designed by © Vassilis Serasidis

Connection of the TV Set to VG/ SVG to a Card - The difficulty of connection vga of a videocard to the TV set is, that Frequency of lower case development (display) of the TV set makes 15 KHz, and VGA card - from 31 KHz and is higher. Translation of development (display) of the TV set up to 31 KHz practically is unreal, because of The large inductance coil and excessive parasitic capacity SPLiT.__
