Sketch the timing diagram for a 4-bit ripple counter which uses T flip-flops. (See Problem 6.2.25)
Problem 6.2.25
(a) For a JKFF with J K = 11, the output changes on every clock pulse. The change will be coincident with the clock pulse trailing edge and the flip-flop is said to toggle, when T = 1, for the T flip-flop. Show JKFF connected as a T flip-flop and its timing diagram.
(b) Using T flip-flops, show the block diagram for a 3-bit ripple counter and its input and output waveforms.
Design the most efficient centrifugal pump that produces 200 gpm (45.5cumeters/hr) water flow rate at 100 psi (680 kPa) head. Specify the impellor diameter and width for a 3400 rpm service.
Calculate the mass of methane that must be burned to provide enough heat to convert 363.0 g of water at 43.0°C into steam at 117.0°C. (Assume that the H2O produced in the combustion reaction is steam rather than liquid water.)
1 kg of liquid water, initially at 40 °C, 2 bar, is heated under constant pressure. If the amount of heat added is 1200 kJ, determine the final temperature and the phase of the system in the final state (if vapor-liquid mixture, report the mass fr..
Water at 20 °C 30 bar is heated in a closed system under constant pressure. If the quality in the final state is 75%, what is the amount of heat?
All that is required is a four-stage counter which, having counted from 0000 to 1001 (i.e., decimal 0 to 9; ten states), resets to 0000 on the next clock pulse. Develop a block diagram of an asynchronous decade counter and show its timing diagram.
For this assignment you will undertake an analysis based on a self-designed fictitious study that utilizes statistical analyses. You will first develop a fictitious problem to examine. It can be anything.
A plating waste with a flow of 50 L/min contains 274 mg/L of NaCN. Determine the amounts of chlorine as Ca(OCl)2 and NaOH required to: (a) Oxidize the cyanide to cyanide; and (b) Oxidize the cyanide to CO2 and H2O.
Consider the following information: i. The layer of dead skin on our bodies is sufficient to protect us from most -particle radiation. ii. Plutonium is an -particle producer. iii. The chemistry of Pu4 is similar to that of Fe3. iv. Pu oxidizes..
Also find the source voltage that would yield I = -8µA.
What Z values correspond to scores of 100, 118, and 140?
The air-film coefficient at the outside of the insulation may be assumed constant at 2.0 Btu/(h)(ft2)(°F) for all insulation thicknesses
It is desired to use 28.32 m 3 /min of air (metered at a pressure of 101.3 kPa and 294.1 K) in a process. This amount of air which is at rest enters the fan suction at a pressure of 741.7 mm Hg and a temperature of 366.3 K and is discharged at a pres..
