4. Given the circuit shown in Figure Q4. (3-bit Ripple Up Counter) Input Clock Pulses No. 1 2 3 4 5 6 7 8 9 10 PRE K FFO CLK CLR 9 5 V (OV to reset) Initialise 1st Clock Pulse 2nd Clock Pulse 3rd Clock Pulse -05V 4th Clock Pulse 5th Clock Pulse QA 6th Clock Pulse 7th Clock Pulse 8th Clock Pulse 9th Clock Pulse PRE K FF1 CLK CLR -05V 5 V (0V to reset) QB a. Tabulate the binary counting sequence for the counter in the table provided below: Clock Pulse Qc 0 0 0 0 1 1 1 1 0 0 J Outputs QB 0 0 1 1 0 0 1 1 0 0 b. From the table, identify all the unique Q output combinations. PRE FF 2 CLK -05V K CLR 9 5 V (0V to reset) Qc QA 0 1 0 1 0 1 0 1 0 1 c. Each of the unique Q output combinations of a counter is known as a counter state. The total number of unique states in a counting sequence is known as the modulus of a counter, or MOD in short. From your results, what is the MOD number of the two-bit counter? Explain. d. How is the number of J-K flip-flops in the counter related to its MOD number?
