Copy a segment of text into MATLAB as a string (you choose the source of the text).
Then write a MATLAB program to count the relative frequency of each character (ignore all characters that do not correspond to one of the 26 letters and do not make a distinction between upper and lower case).
Using the results of your program, calculate the entropy of a source that outputs the 26 English characters with the probabilities you calculated.
Running at 1200 rpm from a 280-V source, a series-connected dc motor draws an armature current of 25 A. The field resistance is 0.2Ω, and the armature resistance is 0.3 Ω. Assuming that the flux is proportional to the field current, determine the ..
Find the total energy stored in the network. Change from uF to uJExpress your answer using two significant figures.
A bom initially at rest explodes into a large number of tiny fragment. the total momentum of all the fragments are
The current entering the positive terminal of a device is 5e-4t A and the voltage across the device is 2 di/dt V. Find the charge delivered to the device between t = 0 and t = 2 s.
Write the characteristic equation of the closed-loop system - Find the frequency at which the system will oscillate when K > 0.
Evaluate a significant experience, achievement, or risk that you have taken and its impact on you.
In designing a low-pass filter for an audio system, the filter stop band attenuation must be at least 40 dB at a frequency that is 2 times the passband frequency. The attenuation in the passband must be less than 1 dB.
What are the most common insulators used for extremely high voltages. Explain your answer with, at least, two points foreach insulator. Hint. they can withstand much highertemperatures than rubber insulation.
An inverting amplifier with resistors R1= 5.6k and R2=120K is fabricated using an op amp with an open loop gain of 10^5. What is the percent difference between the actual gain and the ideal gain
In a balanced three-phase system, the abc phase sequence source is wye connected and Van=120
What happens when you have a non-zener and zener diode in series opposing each other eg non-zener is forward bias and the zener is reverse bias assuming both are ideal (infinite slopes when they are operating).
Compare GBN, SR, and TCP(no delayed ACK). Assume that the timeout values for all three protocols are sufficiently long such that 5 consecutive data segments and their corresponding ACKs can be received (if not lost in the channel)
