In digital electronics and modern computer hardware, a flip-flop is sequential digital circuit used as a basic memory element. It has two stable states and can be used to store state information. One of its states represents ‘1’ while the other represents ‘0’. The most common types of flip-flops are SR-flip-flop, JK-flip-flop, and D flip-flop. When used in a finite-state machine, the output and next state depend not only on its current input, but also on its current state (and hence, previous inputs). Figure 1 D-Flip-flop with clock pulse (CP) Figure 1 shows a D flip-flop with clock pulse (CP). D is directly passed from stage1 to stage 2 through NAND gate and passed as inverted through gate 5 and gate 4. The input D is always sampled when the system CP is 1. Considering the memory element in Figure 1, perform the following tasks: Design FSM for the Figure 1 Simulate the Figure 1 using C. Write 400 words report on shift and…

A, B, C are three input, and all of them are varying, as given below: A = 0 at time 0, and stays constant until time = 20 ns, when it changes to 1 and stays constant there after B = 1 at time = 0, and stays at 1 value until time = 35 ns, and then changes to 0 at35 ns, and stays constant after that. !3! %3D C= 0 at time 0 and changes to 1 at 50ns Plot A, B, C upto time = 70 ns.
A synchronous state machine has two inputs (X1 and X2) and one output (Z). The relationship between the inputs and output is described in the following waveforms. The designer needs for OR-gates for building .......... the circuit of the aforementioned state machine. X1 X2 6. 3 2 4
Computer Science 1. Design a circuit for a digital lock using the minimum number of D latches. The lock has two input push-button switches A, B and it outputs a single pulse (Z1) for each activation i.e. lock open. The two switches are interlocked mechanically so that simultaneous pulses are not possible. The lock should have the following features: a. The opening sequence is 0011. ii. Then replace ‘0’ by ‘A’ and ‘1’ by ‘B’ in the sequence. b. Five B pulses should give an absolute reset. c. Any incorrect use of the A switch will cause an output (Z2) to ring a bell to warn that the lock is being tampered.

JK flip-flops, also colloquially known as jump/kill flip-flops, augment the behaviour of SR flip-flops. The letters J and K were presumably picked by Eldred Nelson in a patent application. The sequential digital circuit shown below shows the design of a JK flip-flop based on two SR NAND latches. Assume the circuit's output is Q = 0 and that the inputs are J = 0 and K = 0, and that the clock input is C = 0. (You can make use of the fact that we already know how an SR NAND latch behaves.) D Co D Ko a) Suppose J transitions to 1 and C' transitions to 1 soon after. Create a copy of the drawing and indicate for each line whether it carries a 0 or a 1. b) Some time later, C transitions back to 0 and soon after J transitions to 0 as well. Create another copy of the drawing and indicate for each line whether it carries a 0 or a 1. c) Some time later, J and K both transition to 1 and C transitions to 1 soon after. Create another copy of the drawing and indicate for each line whether it carries…
• Design a sequential circuit with two T Flip Flops, A and B, and two inputs, E and x. If E=0, the circuit remains in the same state regardless of the value of x. When E=1 and x=1, the circuit goes through the state transitions from 00 to 01 to 10 to 11 back to 00, and repeats. When E=1 and x=0, the circuit goes through the state transition from 00 to 11 to 10 to 01 back to 00, and repeats
Develop a logic circuit necessary to meet the following requirements: In a certain chemical-processing plant, a liquid chemical is used in a manufacturing process. The chemical is stored in three different tanks. A level sensor in each tanks produces a HIGH voltage when the level of chemical in the tank drops below a specified point. Design a circuit that monitors the chemical level in each tank and indicates when the level in any two of the tanks drops below the specified point. The design must include a chip with logic gates and also be written with VHDL code.
There are 5 universal gates. A True B False
Write the word TRUE if the statement is correct If the statement is false, replace the word's that, if substituted for the underlined word/s, would make the statement correct. Flip-flops are asynchronous bi-stable devices because there can only be two states. Negative edged triggered flip-flop has a bubble on the clock input signal which means that the circuit will only respond to negative The S-R flip-flop is a single-input version of the J-K flip-flop formed by tying both inputs together
