Grading policy

	Answers to only a subset of the questions will be graded for
	correctness of the answer and the procedure. Credit will be
        granted for attempting the other questions.

Problem numbers below refer to the textbook by McCluskey.

   (A) Problem 7.10(b), but read "S-R flip-flop" in the problem as
       "reset-dominant S-R flip-flop"
   (B) Problem 8.1(a)
   (C) Problem 8.2(b)
   (D) Reduce the state table given in Table P9.3(b) on page 419,
       assuming:
	(a)  A = - and B = -  
	(b)  A = 6 and B = -

    (E) Design a sequential circuit using D flip-flops
        to multiply a number by 3. The input number will be fed serially
        starting with the least significant bit. The output should be
        produced serially as well (one bit at a time). The number of
        bits in the input number is not bounded, but, if necessary,
        you may assume that an adequate number of 0's is entered
        after entering the number to be multiplied.

    (F) Problem 10.2
