Hello, i am currently working on an attendance system using MATLAB by the comparison of 2 images of the same class, does anyone have any ideas or methods to use

Consider a finite state machine with a control input called mode. When mode = 0, the machine operates as a mod-3 down counter, where the outputs are the count values. When mode = 1, the machine's output progresses through the last 4 digits of your WCU ID (1133) number (1 digit per clock cycle). Complete each of the steps which follow.

(a) Draw the state diagram for this machine.
(b) Write RTL Verilog code which implements this design. Submit your printed source code by the due date and time.
(c) Create a test bench to exercise the design through all of its states and functions. Submit your test bench source code and a simulation waveform. The simulation waveform must show the digits of your WCU ID and no one else's.

1. How many complex numbers z are there such that z³ = 1?

2. Translate x(t) = -cos(πt + π/3) into standard form A⋅sin(2πft + φ) (There are multiple correct answers)

3. If f_s = 100 Hz, what are three aliasing frequencies for f = 80 Hz?

4. A signal x is delayed by one sample and scaled by −1/2, producing a new signal y[n] = −1 2 x[n − 1]. (a) How does Y[m] relate to X[m]? (b) What about |Y[m]| and |X[m]|?

5. If a signal x’s DFT has entirely real coefficients X[m] (has no imaginary component), what can you deduce about x? Consider the phase for each analysis frequency.

6. Let x[n] be a signal with N = 5000 samples. (a) If you compute an STFT with a frame length of K = 1000 and hop length h = 250, what will be the shape of the resulting spectrogram? (b) How would it change if you set K = 2000? (c) What if you set h = 100?

gow does scan expansion mesh and scan expansion meshless work in a oscilliscope?
in other words what happens inside an oscilliscope when i turn the time/div knob?

PN Junctions and breakdown

1. Draw and interpret energy band diagram for pn junction in equilibrium, forward, and reverse bias

2. Describe what physically happens (And why) when you put n-Si in contact with p-Si (e.g., junction formation)

3. Calculate Vo, W, Wn, Wp

4. Describe how/why current flows in forward and reverse bias.

5. Utilize law of junction to calculate the minority carrier concentration just outside the depletion layer

6. Quantify the forward and reverse bias current in a p-n junction given appropriate information

7. Describe the meaning of the diode ideality factor for values of 1 and 2 and in between

8. Describe what constitutes “short diode” conditions

9. Calculate the depletion layer capacitance given sufficient information

10. Identify the two mechanisms that allow for reverse bias breakdown of a diode.

11. Describe what occurs during Zener tunneling and avalanche and the conditions that this will occur

This concept of  (A/D conversion and sampling rates) could be relevant to envisioned future career field.

Could you write a paragraph commenting please?

In MATLAB, the script should use both for and while loops.

Game Mode: Randomly generates 10 unique (e.g. non-repeating) multiplication problems that involve multiplying the integer selected in the previous step by an integer value between 2 and 12, inclusive, after which the following report should be displayed in the Command Window.

You correctly answered __ out of __ problems (__%) involving __s.

The number of correctly answered problems appears in the first blank, the total number of problems appears in the second blank, the percentages of problems answered correctly appears in the third blank, and the integer the user selected in step 1 appears in the last blank.

-- After completing a round of the game, the user should have the option to play another round or quit the game.
