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

an explanation of how a flip-flop circuit operates and the many ways it may be put to use Whether or if the circuit operates in a sequential or combinational fashion.

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

i need the answer with details.

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).

Consider the T flip flop. (a) Using diagram, show how to construct the T flip flop using the JK flip flop. (ii) (b) Determine the Q waveform for a T flip flop with positive clock and the T inputs shown in Figure 5. Assume that Q = 0 initially. Clock

Consider the following circuit with 2 inputs (X and Y) and 2 J-K flip flops.· When X=0, the output (Q1Q0) preserves its value regardless of the value of Y.· When X=1 and Y=1, the output (Q1Q0) counts up by one (00-01-10-11-00 …).· When X=1 and Y=0, the output (Q1Q0) counts down by one (00-11-10-01-00 …).   a) Derive the state transition, output table.b) Derive flip-flop excitations (logic expressions).c) Draw the circuit implementation using only 2-input NAND gates to drive the inputs J0and K0, and only multiplexers (MUX) to drive the inputs J1 and K1.

Design an Octal Counter with D flip-flops. a) Draw the state diagram b) Draw the state table c) Draw the counter circuit

Analyze the following sequential circuit: 1) What type of state machine is this circuit and why? 2) Write equations for flip-flop inputs and output (Y). 3) Derive the next-state equation for each flip-flop from its input equations. 4) Derive the State table. X A' B' LA DA D. A B
