The request
“Draw a 4-to-1 multiplexer using D0 through D3 data inputs, S0 and S1 select inputs, NOT gates for the selects, AND product terms and an OR output gate.”
Then tryAdd an active-low enable input.Change it to an 8-to-1 multiplexer.
What is in this drawing
Read the decisions behind it.
01
Use of intermediate NOT gates for select line inversion
02
Grouping minterms with AND gates
03
Combining outputs with a single OR gate
When teaching or designing combinational circuits from boolean expressions.
