Construct a 4×16 decoder using two 3×8 decoders with active low outputs and one [4 pts] active low enable input, shown below. You are not allowed to use inverters or any additional gates. Question: Construct a 4-to-16 decoder with an enable input using two 3-to-8 decoders with enable inputs and one 1-to-2 decoder with enable inputs. Here’s the best way to solve it. In table 6, the proposed 3-to-8 decoder circuits are compared with their available peers. May 21, 2023 · The 3:8 decoder has an active high output and active high enables using a minimum number of 2:4 decoders. Toffoli Gate: Let Iv and Ov be the input and output vector of a 3*3 Toffoli Gate (TG) [6,7] respectively, where Iv =(A, B, C) and Ov=(P=A, Q=B, R=AB⊕ C). This will give us 8 output lines. The 2-4 decoders can be designed by using TGL or DVL gates as it takes 16 transistors which includes 12 AND/OR gates and 2 inverters. Each of the second row decoder would activate one of its output for each A input, but only the one whose Chip Select (CS) is activated by the first decoder actually will activate its output.
