A sequential circuit has one primary input m, and one primary output n. It has two D flip-flops with inputs D₂ and Do, and corresponding flip-flop outputs Q₂ and Q. It also has a T flip-flop with input T₁ and output Q₁. The circuit is wired in a way described by the following equations: D₂ = m'Q₂Q₁ +mQ₂'Q₁ + m²Q₂'Q₁'Qo' • T₁ = Q₁²Q₁ + mQ₁' + mQ₂'Q' + m²Q₂'Që + m²Q₂Q₁ Do = m'Q₂' + m'Q₁³Qỏ' + m²Q₁Q0 + mQ₂Q₁ Qo' n = Q₂Q₁ +mQ₁' + m'Q₂'Qo' Using the sequential circuit, perform state minimization by implication to reduce the number of states to a minimum. Which states are equivalent? In the minimized circuit, how many flip-flops are needed to implement the circuit?

A sequential circuit has one primary input m, and one primary output n. It has two D flip-flops with
inputs D₂ and Do, and corresponding flip-flop outputs Q₂ and Q. It also has a T flip-flop with input
T₁ and output Q₁. The circuit is wired in a way described by the following equations:
●
D₂ = m'Q₂Q₁ + mQ₂'Q₁ + m'Q₂'Q₁'Qo'
T₁ = Q₁'Qo' +mQ₁' + mQ₂'Q' + m'Q₂'Qo + m'Q₂Q₁

●
●
Do = m'Q₂' + m²Q₁³Qo' + m²Q₁Q0 + mQ₂Q₁ Qo'
1
n = Q₂Q₁ +mQ₁' + m'Q₂'Qo'
Using the sequential circuit, perform state minimization by implication to reduce the
number of states to a minimum. Which states are equivalent? In the minimized circuit, how many
flip-flops are needed to implement the circuit?
