You have a 3-to-8 line decoder, an 8-to-3 priority encoder, an 8-channel multiplexer, and an 8-channel demultiplexer. Which would be most appropriate to use in each of the following situations. 1. A 6-position rotary dial provides an active signal on exactly one of its 6 outputs at a time. You want to use fewer wires to represent the switch position. 2. A digital signal from a microphone needs to be routed to one of seven classrooms so that you can...
