Hi maybe someone can help me here, basically I am trying to build a computer controlled coaxial switch. I am using a regular Integrated circuit multiplexer to handle which channel is patched to output. So basically I have:
(8 X Coaxial Inputs) I I I I I I I I
microcontroller ----> | Multiplexer | --------------- I (1 X Coaxial Output)
The idea is so that I can use a computer to control which of my 8 video feeds that I can watch. I thought that because the connections are straight through I wouldn't have to worry about attenuation as much, but I tried a sample setup using a breadboard and I can barely see the picture. Any ideas as to how I can make it work?
I am currently using a breadboard with all the components I listed Plus some small gauge cables (so that they fit on the bread board)
UPDATE: This is what My setup Looks like http://img6.imageshack.us/img6/6320/49195403.png the MUX is a UTC 4051 Data Sheet is Here http://alldatasheet.com/datasheet-pdf/pdf/173652/UTC/4051.html
