A buck converter has the following parameters: Vs = 24 V, D = 0.65, L = 25 uH, C = 15 uF, and R=10 ohm.The switching frequency is 100 kHz. Determine (a) the output voltage, (b) the maximum and minimum inductor currents, and (c) the output voltage ripple.
Contemporary computers often have more than 100mb of physical memory. Suppose the page size is 2 KB. How many entries would an associative memory need in order to implement a page table for the memory
The controlled variable in a closed-loop system is the direction of a robot arm. Initially, it is at 50o; then it is commanded to go to 25o. What is the error when the arm position is at 15o
Use as many components as you can to to minimize adders delay. Show the entire Divide and Conquer Tree in which it is clear for each break up node in the tree, whether the stitch-up is a "wake" up or "speculation"
Consider the transformer to deliver its rated kilovoltamperes at 0.80 power factor lagging to a load on the low-voltage side with 240 V across the load. Find the highside terminal voltage.
A 440-V three-hase Y-connected synchronous motor has a synchronous reactance of 1.5 ohms per phase. The field current has been adjusted so that the torque angle is 28 degrees when the supplied power to the motor is 90kW.
In a multiuser CDMA system of DSSS, all transmitters are at equal distances from the receivers. The additive white Gaussian noise density Sn(f) = 5x10^-7 W/Hz. BPSK is used by all users with bit rate = 16 kb/s. There are 16 users.
Resisitive load, A 4:1 step down transformer uses a 60Vac source on the primary windings.
select a window function to limit the number of samples of an infinite impulse response and the filter specifications are the same, regardless of which window function you select. If you are given the option of using either a Hamming
(a) Determine a unit vector in the direction of Q at P(1, 2, 1) (b) Find the component of Q at P in the direction of PT where T is point (5, 3, -4) (c) Where is Q the same as the unit vector of \(a_{x}+11a_{y}+10a_{z}\)
initially at a temperature of 17c and a pressure of 100 kpa air occupies a volume of 3.0 m 3 in a rigid vessel.a valve opens allowing air at 600 kpa and 17c to enter until equilibrium is reached final temperature is found to be 77c
