Hi all,
I'm designing a 3 way analog channel selector (for audio frequencies) and I've designed a logic circuit that will so the individual channel selection just fine. It uses a schmitt trigger IC, an or gate IC, 3 transistors, 3 dual cathode diodes and a couple of resistor, amongst other parts.
I see no reason to use a microcontroller other than it might potentially be a little more reliable (...speculative?) so I'd like some feedback from you guys!
Realistically, the circuit should take three inputs - from switches, and when one switch is pressed, the corresponding output should be latched e.g. if switch A is pressed, input A is routed to the output.
