Hi, new to the forums here. I'm looking for some help with multiplexers. I've created a 128-to-1 multiplexer with 8-to-1 multiplexers and one 2-to-1. Basically I have 16 8 to 1 in the first batch, 2 8 to 1 in the second and then a 2 to 1 to combine the last two. I'm assuming that's correct.
Here's my question. I need to tabulate the output as a function of the selection switches. Does anyone know how to do that? I've seen some truth like tables for 2 selection switches for a 4 to 1, but nothing this big. I'm assuming that I have to have 7 selection switches as 128 is 2^7. Please help! Thanks!
