- T0 And T1 Flip Flops 1 (43.04 KiB) Viewed 29 times
We want to design a modulo-3 counter by designing appropriate logic to apply to the To and T1 inputs of two T flip flops as shown below: Input logic Oy To Qo Input -logic 1 TAQI Ck H Сk 0. . The counter should follow the count sequence Q1Q0 = 00 01 +10 00 01 +10, etc.... If at any point Q1Q0 = 11 (this could occur at turn-on of the circuit, as the initial state of the flip-flop at tum on is random and unpredictable) then the system should transition on the next clock cycle to Q1Q0 = 01. Extract the required logic for the input to To: OTO - Q1 To = 20 To = 91 +Q0 To = Q1 20 Extract the required logic for the input to T1 O T1 = 21 OT - Q0 O T1 = Q1 +Q0 OT - Q1-Q0
