A causal LTI system has the difference equation y[n]+0.25y[n-1]-0.125y[n-2] = x[n]+x[n-1].What is the impulse response of this system and what is it's output y[n] for input signal x[n] = (-1)^n u[n].
Design and implement a Rectangle class. Make your class inherit from the Point class given in the lecture (notice that a rectangle can be described through the upper-left vertex, the height, and the width).
A fair 6-sided die was tossed in a fair way 5 times. a. What's the probability of getting the sequence of outcomes 1, not 1, 2, not 2, 3 b. What's the probability of getting exactly two 6's in the sequence of 5 tosses
Calculate the extraction efficiency (in percentage) of flat - surface LED without any encapsulation (emits directly into the air). The LED is fabricated from material with the refractive index n = 2.3.
(Probability of negative lifetime is negligible) Lifetime of chip 2 is also a Gaussian RV with mean 22,000 and standard deviation 1000 hours. Which is preferred if the target lifetime of the system is (i) 20,000 hours and (ii) 24,000 hours
Recall that for discrete sequences the ts sample period (the time period between samples) is the reciprocal of the sample frequency fs. Write the equations, describing time-domain sequences for unity-amplitude cosine waves
What is the difference between a D flip-flop and a J-K flip-flop How does the number of inputs affect the possible synchronous states of a flip-flop (Set, Reset, Hold, Toggle)
An induction motor has an output or shaft power of 30 kW at 86% efficiency. For this operatingcondition, stator copper loss = rotor copper loss = core loss = mechanical rotational losses. Determine the slip.
If the efficiency of the motor and drive system is 80% and it is fed through a transistor regulator at 12V, what is the mean current through this regulator when the printer is working continuously?
By direct integration find the Laplace transforms and the region of convergence of the following functions
On a breadboards, hook up an IR LED to provide an infrared light source for signaling the phototransistor as shown in Figure 2 below. Use a pushbutton switch to turn the IR LED on and off.
