Problem #1
Can one build an RS flip-flop using one NAND and one NOR, wired together in a feedback loop, similar to the NAND-NAND or NOR-NOR RS flip-flop?
Why, or why not?
Problem #2
Given the circuit above, which uses 74LS74 D flip-flops, complete the timing diagram below and show how Q0, Q1 and Q2 behave as a function of time. Assume that the timing diagram below shows the time the circuits were powered-up at the left end of the time axes.
