6. Assume that we are working with a sequential circuit that takes a single input X, and in turn manipulates a JK flip flop and a D flip flop. It is pictured below. Draw the characteristic table (i.e., the extended truth table) for the circuit, using the column headers in the order X, D(t), JK(t), D(t + 1), JK(t + 1), where t and t + 1 refer to the value output on the Q line in the current cycle and the next cycle respectively. You can assume that the clock signal is being passed to the flip flops on each clock tick (i.e., in the normal fashion). X D 08 J >C K Q ?

Considering an edge triggered T flip-flop, answer the following THREE questions (a) Write out its characteristic table (b) Suppose it is a POSITIVE edge triggered T filp-flop, draw out the timing diagram of Q (the initial state of Q is 0).

Draw the finite state maching diagram of the following: The system detects sequence of ‘1001’ on a single input ‘b’ to the system, and asserts ‘1’ on output ‘x’ for one cycle. Otherwise, output ‘x’ remains ‘0’. Design a lock system that takes input from four independent buttons (R, G, B and O). The Lock signal should be asserted high, only when the buttons are presses in the following order (GàBàRàO). Otherwise, the system should asser Error signal high for one cycle and initialize itself.

Q: For the S-R latch , use four inputs and find the truth table which are either set or rest , draw the schematic diagram and main block diagram ?
Implement the diagram in part b and verify its function experimentally by constructing a truth table from the test data.
In the diagram above, the inverter (NOT gate) and the AND-gates labelled 1 and 2 have delays of 9, 10 and 12 nanoseconds(ns), respectively. Wire delays are negligible. For certain values of a and c, together with the certain transition of b, a glitch (spurious output) is generated for a short time, after which the output assumes its correct value. The duration of the glitch is 1 2

Task: DL34. In digital electronics, a NAND gate (NOT-AND) is a logic gate which produces an output which is false only if all its inputs are true; thus, its output is complement to that of an AND gate. A LOW (0) output results only if all the inputs to the gate are HIGH (1); if any input is LOw (0), a HIGH (1) output results. A NAND gate is made using transistors and junction diodes. Minimum number of NAND gates required to implement the following binary equation (A'+B') (C+D)?
Create a truth table (with PRESENT/NEXT states & Control D Inputs) for the following state transition diagram: The state transition diagram provided was obtained according to the information given in the problem below. Design a control unit (using D flipflops) for a coin operated machine. A candy costs 20 cents and the machine accepts nickels and dimes. Change should be returned if more than 20 cents is deposited. No more than 25 cents can be deposited on a single purchase (therefore the maximum change is one nickel). The inputs are nickels and dimes, and the outputs are the candy and the change.
