Consider the following 4×1 multiplexer with inputs:
w0=2, w1=1, w2=x2' and w3=0
And with switches:
S1 x1 and S0=x0
What is the multiplexer output f as a function of x2, x1
and x0?
I need help adding a capacitor and a Zener diode to my circuit. I’m looking for a simple sketch or diagram showing how to connect them. i want diagram with final circuit after adding the zener diad and capacitor. don't do calclution or anything. thanks
