a summary of what a flip-flop circuit accomplishes and how it may be used

Write the next-state equations for the flip-flops and the output equation. (b) Construct the transition and output tables. (c) Construct the transition graph. (d) Give a one-sentence description of when the circuit produces an output of 1. Q2 D2 Q1 T1 CLK Figure 4

Using 4 J-k flip flops explain how a counter can be built with the aid of a diagram

5. JK flip-flops are often used to build counters. The JK flip-flop will toggle the original output value when triggered by the clock signal if both the J,K inputs are connected with a constant "high"(logic 1). All the JK flip-flops in Figure 2 are negative edge triggered. All the initial values of Q2Q1Q0 are 0. Qo (LSB) (MSB) Input K K Logic 1 Input Q2 000 Figure 2. Counter (a) Sketch the output waveforms forQ2 Q1 Q0. Write down the output binary value (Q2Q1Q0: such as "000", "001") for each clock period on the figure. (b) Describe the function of the counter (e.g. binary down counter counting from 7 to 0).
