1. Simulate the sequential circuits you built using the T and D Flip-Flops (Fig. F.2.1 and Fig. F.3.1) using Logisim. If your lab group number is even, submit the screenshots of your circuits with the Flip-Flop states set to 00 and if your lab group number is odd, submit the screenshots of your circuits with the states set to 01. 2. Draw the IC diagram for the logic circuit in Figure F.1.1
