Write a VHDL model for one flip-flop in a 74HC374 (octal D-type flip-flop with three-state outputs). Use the IEEE-standard nine-valued logic package. Assume that all logic values are ‘x', ‘0', ‘1' or ‘z'. Check setup, hold, and pulse width specs using assert statements. Unless the output is ‘z', the output should be ‘x' if CLK or OC is ‘x', or if an ‘x' has been stored in the flip-flop.
Use the initial and final value properties to find the initial and final values of the waveform corresponding to the following transform.
Consider the signal x(t)=e^-at where a is a positive number. Determine the Fourier Transform of and plot both the magnitude and the phase angle as a function of the frequency.
The treasure map in the figure gives the following directions to the buried treasure: "Start at the old oak tree, walk due north for 530 paces, then due east for 130 paces. Dig." But when you arrive, you find an angry dragon just north of the tree..
You have a laundry room where the following loads are connected to a 208V circuit: 2500W electric base board heater, 600W wash machine, 3600W dryer, and a 1000W iron. All loads are connected in parallel.
For the following voltage and current phasors, calculate the complex power, apparent power, real power, and reactive power. Specify whether the pf is leading or lagging.
design a counter which runs from 2 to 12 usingD-flip-flop. My doubt was whether to consider the unused state asdont care or to link to next state, meaning self correcting.When imake it as self correcting there are too many expressions.
How does a colpitts oscillator works an also explain the principle
A 3.0 μF capacitor is charged to 40 V and a 5.0 μF capacitor charged to 18 V are connected to each other, with the positive plate of each connected to the negative plate of the other. What is the final charge on the 3.0 μF capacitor
For each of the following functions, put the equation in the form of a Shannon decomposition. Create a pass transistor schematic to implement the function. Count the number of NMOS and PMOS transistors and the number of inverters.
A short circuit across a current source draws 15 A. If a 10resistor across the source draws 13 A. What is the internal resistance of the source
It is required to design a peak rectifier dc power supply(i.e. one that uses a filter capactor) that provides an average dcoutput voltage of 15V on which a maximum of ±1V ripple isallowed. The rectifier feeds a load of 150Ω.
Find a simplified expression for y(t), the output of the reconstructor. Can this system operate in "real time"?
