Question

Today's problem Combination circuit

In the following logic circuit, inputs a and b were as shown in the blue diagram on the right in each time period T1 to T6. Which of c1-c5 is the correct output c?

Tip: 1 Let's derive a logical formula. 2 Let's make a truth table. The waveform obtained from 32 and the waveform of c1-c5

Let's compare.

Т1 Т2 T3 T4 15 T6 1 а о А) 1 b 0 Т1 T2 T3 T4 T5 T5 ТВ 1 с1 0 — 1 - с2 0 1 5 c3 0 — 1 с 4 0 1 c5 0
