Can't solve Dmux

[kingofbuffs]

Hello everyone.

Can someone please explain to me how I can figure out  the demultiplexor  from the truth table below? Because there are two outputs, doing the same thing I did with the multiplexor doesn't work. Please help me solve this.



Thank you in advance.

Think of it as two separate problems packaged in one device.

Could you please be more specific? I can not really find the canonical representation of the gate, hence why I am having difficulties finding the solution.

Thanks in advance.

I think what WBahn means is to look at it as two tables, each with both inputs from the original table, but only having one of the outputs.

What if I gave you two separate problems?

The first problem has inputs S and D and outputs Y1. Could you design a circuit to do that?

The second problem has inputs S and D and outputs Y2. Could you design a circuit to do that?

Could you take the solutions to these two problems and put them into a box having two inputs, S and D, and two outputs, Y1 and Y2?

Jesus I solved it. I didn't really expect doing this since I cheated on mux. (I went back and solved it myself after learning how to derive it from the canonical representation though.)

YEAH SCIENCE!

Thank you guys so much!

Thank you guys for asking and answering this topic. I got stuck on this same problem and nothing on google tells me how to implement Dmux using other basic gates only the reverse :()
