[SOLVED] Digital logic cs211 assignment 4

1. Obtain the simplified input equations for a sequential circuit that uses T flip-flops and
is specified by the state diagram below. Write down the necessary procedure. (No need
to draw the logic diagram)
2. Design a FlipFlop with the function table described below. Apart of the clock input, the
FlipFlop has two inputs G and In. Write down necessary design procedure as we learnt in
class and then draw the block diagram. (Using DFF show in the graphic symbol with extra
basic gates).
3. Design a sequence detector using JKFFs to recognize the occurrence of a particular
sequence of bits (1101) (using Moore machine, non-overlapping mode), write down the
necessary procedure for your design (No need to draw the logic diagram)
4. (25 points) Design a sequence generator to generate the sequence 1011110 (starting with
MSB) with minimum number of Flip-flops. Write down all the steps and draw the logic
diagram (Graphic symbol of DFF can be used).
5. (30 points) Design a counter with T flip-flops that goes through the following binary repeated
sequence: 0, 1, 3, 7, 6, 4. Derive the input equations for the FFs. Show that when binary
states 010 and 101 are considered as don’t care conditions, the counter may not operate
properly. Find a way to correct the design.
