2 Timing Analysis [CSC1410 96-97 Q7] Complete the waveform Y1 and SYNOUT for the given sequential circuit CK ASYNIN Y 1 SYNOUT S R D C ASYNIN Y 1 SYNOUT CK
3 [CSC1410 00-01 Q3] Draw a state diagram for the state machine whose behaviour is summarised in the following state (excitation) table. Don’t forget to show the don’t care terms. Marks will be deducted if “d’s” are not used at the appropiate arcs.

Unformatted text preview: repeat a) How do you make the counter count two 000’s which is followed by different binary numbers? (2%) b) How many flip-flops do you need? (2%) c) Draw the transition table. (6%) d) Use positive edge triggered D-type flip-flops for your counter. Sketch the block diagram of your counter. (4%) e) Solve the equations for the inputs to flip flops X1 and X2. (6%) 5 Tutorial Questions [CSC1410 96-97 Q5] For the following sequential circuit, determine the output sequence for the input sequence X = 0 0 1 0 1 1 0 1 0 1 if the starting state is A.
