a) Write the VHDL code for a 2-bit( two flip-flops) down-counter with a synchronous reset, using D FlipFlop.
b) Based on your VHDL code, and assuming D-Flip Flops, draw the logic circuit that you believe will result after some commercial VHDL compiler and synthesizer has been used to run your code.
c) Using your knowledge of ‘State Machine' design from logic design principles, draw the state diagram for the 2-bit down-counter, generate the state transition table, the flip-flip input equations for D Flip Flop, and finally the logic diagram of the system.
Design a DC power supply that provides -95v +/- 5v to a 2 amp load (energy absorber). The input source is a 100 volt peak sinusoid, 60 Hz. You may use any circuit element we've studied. State the values of all circuit elements
Determine the current through each of the impedance elements given below. Assume an applied voltage of 480 ? 30o V. Express your answers in polar form. a. Z = 50 + j0Ω b. Z = 20 + j15Ω c. Z = 30 - j25Ω
A wire is bent in the form of a half loop of radius a=10mm and charged with a line charge density pL=10^-9 C/m. Calculate the field intensity at the center of the loop.
Consider a VBE multiplier with R1=R2= 1.2k ohms utilizing a transistor that has VBE= 0.6V at Ic = 1ma, and a very high beta. (b) Find the value of the current I that will result in the terminal voltage changing (from the terminal voltage 1.2-v val..
The following 4 differential equations describe mass spring systems. Identify each system as either undamped, overdamped, underdamped, or critically damped (Justify your answer). Determine the angular frequency and period for the undamped and the ..
write a program that calculates the quadratic equation. the program should be able to compute imaginary numbers (i.e. sqrt(-1)). finally, output the tow result. hint: the computer cannot directly compute imaginary numbers
DC-DC converter. You have 10 capacitors, each 1F. If you charge them in parallel from a 5V power supply, and then disconnect them and reconnect them in series: a. What is the equivalent capacitance seen by the power supply while charging.
This document is shown a paper on Orthogonal frequency-division multiplexing with advantages, disadvantages and uses.
An incident -ray photon is scattered from a free electron that is initially at rest. The photon is scattered straight back at an angle of 180 degrees from its initial direction. The wavelength of the scattered photon is 9.00×10^-2 nm.
An uncharged capacitor and resistor are connected in series with a 12V source and switch. What is the voltage across the capacitor after the switch is closed and the capacitor is fully charged
A curve of radius 159 m is banked at an angle of 11°. An 810-kg car negotiates the curve at 93 km/h without skidding. Neglect the effects of air drag and rolling friction. Find the normal force exerted by the pavement on the tires.
Assume that there is a resistance of 2.70 k in a system and there is a current of 2.2 Amps flowing thru it. How much energy is consumed by this component in 24 hours
