To digitally manipulate information we must encode it using binary numbers. Consider an encoding for playing cards. There are 52 cards in a deck and they are divided into four suits with values from 1 to 13 (an Ace is 1, Jack is 11, Queen is 12, King is 13). Show two possible encodings for the cards.
A 150 MVA, 24 kV, 125% three-phase synchronous generator supplies a large network. The network voltage is 27 kV. The generator operates with an induced voltage, which is twice the rated line-to-neutral voltage.
Pulse Generator, Using one 555 timer, design a pulse generator that will have the following continuously variable ranges
The terminal voltage of the battery is v=11 +0.5t for t>0. a. Find the energy delivered to the battery during the five hours. b. If electrical energy costs 10 cents/k Wh, find the cost ofcharging the battery for five hours.
The tuning capacitor of a Wien bridge oscillator is 100 pF and the frequency is 5 kHz. To what value of capacitance pF should the capacitor be changed to if the frequency is to be changed to 2 kHz
When working out the power dissipated you have the equationusing the same current (io) but this time you use anegative sign in the equation. How do you know when to use a positive or negative sign for this current in both situations
The repulsive force one exerts on the other when they are 20cm apart is 1.35 X 10-4 N. after the balls are touched together and then represented once again to 20cm, now the repulsive force is found to be 1.40 X 10-4 N. find the charges q1 and q2.
If the machine is driven at a speed of 459rpm to act as a generator of real power, find the rotor current referred to the stator and the real and reactive power outputs of the induction machine.
Calculate A - B for the pair of numbers, 1101011, 0101010 assuming a two's complement number system and that the numbers are stored in one byte of memory. The numbers are in un-complemented form.
A 10kO potentiometer sensor is used to measure displacement and is connected to a voltage source of 5V. The full range of the displacement is 10mm. When the potentiometer is at 4mm of its maximum displacement.
Brown and Vranesic. Problem 6.28 - Repeat Problem 6.26 using T flip-flops. Design a three-bit counterlike circuit controlled by the input w. If w = 1. then the counter adds 2 to its contents, wrapping around if the count reaches 8 or 9.
a. Evaluate X(s) and specify its region of convergence. b. Determine the values of the finite numbers A and t0 such that the Laplace transform G(s) of g(t) = Ae^âˆ'5tu(âˆ't âˆ' t0)
A 35 kHz sinusoidal voltage has zero phase angle and amaximum amplitude of 10 mV. When this voltage is applied across theterminals of a capacitor, the resulting steady-state current has amaximum amplitude of 644.73 microAmps.
