Write a for loop from 1 to 3 using i as the variable. For each value of i:

Create a vector x of 10 random numbers between 0 and 1. Create a second vector t which is equal to ten integers from 1 to 10. Plot x versus t in figure 1. Use hold on to keep each plot. Use a different color for the line for each value of i.

At the very end, add the text 'time' using xlabel to the horizontal axis, and the text 'f(t)' using ylabel to the vertical axis.

This is what I have so far:

% Creating a 'for' loop from 1 to 3 using 'i' as the variable
for i=1:3
% For each value of 'i', creating a vector 'x' of 10 random numbers between 0 and 1
x=rand(1,10);
% For each value of 'i', creating a second vector 't' which is equal to 10 integers from 1 to 10
t=randi([1,10],10);
end

% Plotting 'x' versus 't' in figure 1
figure(1),plot(x,t)

% Using 'hold on' to keep each plot
hold on

% Using a different color for the line for each value of 'i'
%add code

% Adding the text 'time' using 'xlabel' to the horizontal axis
xlabel('time')

% Adding the text 'f(t)' using 'ylabel' to the vertical axis
ylabel('f(t)')

1. With all those self-driving taxis scooting around, it would be nice if you could hail one just by giving the usual hand signal as it approaches -- rather than having to use a cell phone to make the pick-up request. You would like to build a system using a camera and quite a lot of image processing computation to recognize when a human is hailing. The currently best processor you can buy isn't fast enough to do this computation before the taxi has driven past the person who wanted a ride. Fortunately, your business plan says you don't need to ship your first product for two years. How would you go about figuring-out if fast enough versions of that processor will be available in two years when your product needs to ship? (Note: there are lots of valid answers to this question.)

What are the advantages of Wheatstone bridge measurement over a direct resistance measurement if for a temperature sensor?

Exercise 2.1: Basic digital signals (a) Write a MATLAB program to generate and display (using the stem function) the signals defined in Table 1. The MATLAB code of the first signal (dirac) is given in the report template as an example. (b) Write a MATLAB function [x, t] = sin_NU(f0, fs, T) to generate a sine signal. The output parameters x and t are the signal and time vectors, respectively. The input parameters are f0 (signal frequency in Hz), fs (sampling frequency in Hz), T (signal duration in sec.). (c) Test your sin_NU function with the input parameter values .... and display the result using the plot function. List of basic digital signals to generate: - Dirac (Unit Response) - Unit step (Heaviside step) - Sign - Rectangle - Sine - Sine cardinal Exercise 2.2: Audio aliasing To illustrate the aliasing phenomenon, let’s perform two simple experiments allowing us to “hear” it. Using the sin_NU function of Exercise 1: (a) Generate two 1 kHz sine signals (2 seconds duration), first signal at 20 kHz sample frequency and second signal at 1.5 kHz sample frequency; (b) On the same graph, use the plot function to display the two signals versus t in the range 0 < t < 5 msec.; (c) Listen to the two signals one after another using the function soundsc(x, fs); and (d) Give your interpretation of this listening. Exercise 2.3: Quantization Quantization is done by replacing each value of an analog signal x(t) by the value of the nearest quantization level. To exemplify this operation, let’s simulate an unipolar ADC (Analog to Digital Converter) having the technical specifications: R = 10 Volts (full-scale range) and B = 3 (number of bits). (a) Write a MATLAB function y = adc_NU(x, R, B) where x and y are vectors containing the input signal and the quantized signal, respectively; (b) Test your function with an input ramp signal ranging from -5 to 15 Volts (1 volt per step); and (c) On the same graph, use the plot and stem functions to display the input signal and quantized signal, respectively.

What is the most effective way to reach both the users and IT department staff about how important security policies are?

A robotic arm is controlled by several stepper motors.

Stepper motor (or step motor) is a brushless DC electric motor that divides a full rotation (360 degree) into a number of equal steps (10 degree/step in this case). The motor's position can then be commanded to move and hold at one of these steps without any feedback sensor (an open-loop controller). This motor usually has 4 wires. To move a motor, the following bit patterns should be applied to these 4 wires.

Clockwise rotation: 1100à0110à0011à1001 and these 4 patterns repeated again such as à1100à0110....

Counter clockwise rotation: 1100à1001à0011à0110à and these 4 patterns repeated again such as 1100à1001….

Each input pattern (for example 1100) moves motor 10 degree. Assume the first four bits (least Significant bits) of register R2 are connected to one these motors.

Write a program in LC-3 assembly language, to do the following:

If you type “1” motor moves 120 degree clockwise (sending 12 patterns) and then 90 degree counter clockwise (sending 9 patterns). If you type “2” motor moves 50 degree counter clockwise (sending 5 patterns).

Depends on what number you enter; the console should display all the related patterns sending to the motor.
