Repeat Problem 1-22 using MATLAB to perform the calculations. Create a vector for the voltage values, v = [15 5 10 -10 20 20], and a vector for the current values, i = [-112 -1 -3 2].
Compute the corresponding vector for the power values, p, using element-by-element multiplication (.∗) and then use the sum command to verify the power balance.
Describe the two spin echo methods (1.Hahn, 2. CPMG-Purcell et. al). Describe the role of p/2 and p pulses in each case and make a comparison and contrast. Give diagrams
Design a counter that counts pulses on line 'w' and displays the count in the sequence 0,1,3,2,0,1,3,2,0,1. Use D flip-flops in the circuit.
A torque of 10 N.m is applied to a uniform disk shaped flywheel. The flywheel has a mass of 20kg and a radius of 0.5m. At t=0, the flywheel is at rest. How much energy is stored in the flywheel at the end of 20 sec
A carousel, starting from rest, is brought to a full rotational speed of one revolution per 5.00 seconds. The angular acceleration during the process is 0.300 rad/s2. The radius of the carousel is 6.00 m.
What bit pattern (after you remove the beginning and ending flags and any stuffed bits) will the receiver pass on for higher level processing?
With the 1s complement scheme, how does the receiver detect errors? Is it possible that a one bit error will go undetected? How about a two bit error?
question 1ai give three advantages of a three-phase system over a single-phase system.ii there are two basic
Find the input torque to the generator.If armature current and field current are kept constant, find the new value of the terminal voltage if the power factor is changed to 0.7 lagging.
digital radio link has a bandwidth of 8 kHz and support a transmission of 87 kbps. According to Nyquist how many bits per symbol are required to modulate the signal Remember to use an integer number of bits.
First, generate an array of 20 input random integers in the range between 0 to 30 and display. Then, sort the generated 20 random integer numbers in ascending order using "THE SELECTION SORT" method and display your sorted output data flow chart.
A nickel-iron ring withcross-sectional area 0.85cm2 is expected to be driven to itssatur-ation magnetization of 1.1T in a ?eld of 800 A/m. The ?ux density will be measured by an electronic ?ux integrator with input resistance of 1kOhm
Determine the armature current buildup as a function of time, if the generator voltage constant Kg = 50 V per field ampere at rated speed.
