- Make a 4-to-16 decoder and show its circuit diagram in both ways:
-Create every minterm via multiple 4-input AND gates.
-Employ hierarchical design, use smaller decoders and two groups of 8 AND gates.
Homework Answers
A decoder is a combinatorial circuit that converts binary information from the n coded inputs to a maximum of 2n unique outputs. The question is about 4-to-16 decoder, i.e., 4 inputs to 24 = 16 outputs. We have to use 16 AND gates for the minterms. Let the inputs be A0, A1, A2, A3. Each Di = A3A2A1A0.
Following is the 4-to-16 decoder
This 4-to-16 decoder can be formed using two 3-to8 decoders. Following is a 3-to-8 decoder
Now we can use two such decoders to construct a 4-to-16 decoder as follows

2. Make an 8-to-1 multiplexer with a 3-to-8 decoder and two groups of 8 AND gates each, plus an OR gate. The 3-to-8 decoder must be done with hierarchical design and several AND gates. You are strongly advised to use Logic Works 5 or similar circuit design software to create circuit diagrams for this question. For hierarchical design, you can draw over the exported circuit diagram to outline smaller hierarchical parts
