so, I have to multiplex five analog signals in the range of -2V..2V from { Source0, Source1 } to Target0
Target0 <= mux( Source0, Source1 ) on select
What do you suggest to physically implement the multiplexer? Micro-rele'?
I have never done something similar, but I know it's similar to the technology used to implement KVM for computers.
A KVM (that doesn't stand for Kernel virtual machine or similar staff) is a device that multiplex two or more computer's keyboard's and video's sources (from computers) to a physical input/output devices (the physical keyboard and mouse, and the CRT/LCD).
Now, for the VGA, these signals, concerning the RGB, are analogic, while the synchronism is digital, as well as the PS/2 signals are completely digital.
In my case, I have 5 analog signals... I can't use a KVM, but I can "copy" its idea
