Calculate several samples of the unit impulse and impulse responses of y(n) = -0.75 y(n–1) + x(n) – 0.3 x(n–1) – 0.4 x(n-2).

Re-write the equation in standard form and then indicate the name of each coefficient (a₁, etc.). Use the filter() function in MATLAB to check your results to 1 and 2.

I blurred a grayscale image using a 5x5 average filter and then I am supposed to deblur using an Inverse filter using Constrained Division. Is there a better way to do this?

The error that pops up is this:

 Error using  ./ 
 Complex integer arithmetic is not supported.

 Error in test2 (line 12)
 fbw = fftshift(fft2(blur))./bw;

When I blur the image using a butterworth filter it works just fine yet when I blur using the average filter my code won't work. Below is my attempt:

 clear
 I = imread('buffalo.png');
 H = fspecial('average',[5 5]) ;
 blurred=imfilter(I,H);
 blur=im2uint8(mat2gray((blurred)));
 imshow(blur)

 d = 0.01;           
 bw = blurred;        
 bw(find(bw<d)) = 1; 
 fbw = fftshift(fft2(blur))./bw; 
 ba = abs(ifft2(fbw)); 
 unb01 = im2uint8(mat2gray(ba));

Make a table that summarizes results over the last four years (2013-2017 only) in understanding degradation in amorphous silicon solar cells. The table should have two columns: (1) Brief description of the main results in the paper, and (2) Reference for the paper

Create a simulink model of the nonlinear equation (1) and obtain a plot from 0 to 3 seconds of the

pendulum problem. Be sure to include a scope box so the displacement plot can be viewed.

d2q/dt2 + (g/L)*sinq = 0

q = angle of displacement of the pendulum [rad]

g = gravitational constant 9.81 [m/sec2 ]

L = pendulum length [m]

      The sinq term introduces the nonlinearity. This makes the solution difficult. To simplify the problem,       equation is linearized by using the approximation that sin q = q. This is a valid approximation for small angles of q only. Run

and create a scope plot for displacement vs time for approximately 5 cycles of a 0.5 m long pendulum that has a starting angular displacement of 10 degrees and an initial angular velocity of – 10 m/sec. Note use the linearized equation.

How would you design a cache coherence with only MS, not MSI. How do you manage the new protocol?

Draw the new MS protocol. For each state, show all the relevant transitions.

In the new MSI protocol, when does a memory read occur? Specify the bus transaction, the requestor's start and end states, and the states of the other caches if relevant.

In the new MSI protocol, when does a memory write occur? Specify the bus transaction and the requestor's start and end states. Specify any other scenario where a memory write occurs.

Consider the following discrete memoryless channel: Y = X + Z, where Pr{Z = 0} = Pr{Z = a} = 1/2 and the alphabet for x is {0, 1}. Assume that Z is independent of X.

a) Find the capacity of the channel in terms of a.

b) Explain how capacity is affected by a in terms of signal-to-noise ratio (SNR).

Create a counter that continuously counts odd numbers backwards (i.e from ‘F’ to ‘0’) and display it on 7-sd by using the Verilog code.

On this part, you are required to use the clock from the FPGA board. However, the clock frequency is 100 MHz, and it is too fast to be used (10 ?s). Thus, we need to derive a slower clock with a speed of almost 1 s, which the frequency of it is 1 Hz. This process is called clock division.

MY FPGA is BASYS 3 and program must be written in verilog. Could you please help me? At least write the design code.

If you help me, I will be the happiest person in the world.

question 4. For each of the f0 frequencies in Problem 3(c), construct a sinusoidal signal that is turned on at t = 0 and sampled at 100,000/ 2? Hz over the interval ?0.5 ? t ? 0.5 . Again, using Matlab’s convolution command, determine the amplitude and phase (relative to the input) of the response of the filter. Ignoring edges of output that are subject to numerical artifacts. Compare and contrast your answers to those obtained in Problem 3(c).

3. Suppose the transfer function of a low-pass filter with frequency specified in cyclic frequency f is given by H ( f ) = 100/ (100 +i2? f ):

a. Manually find and sketch the amplitude and phase spectra (on regular, non-log scale) of the transfer function.

b. If the input to the filter is x(t) = Acos (2? f0t), derive the general expression of the output. (Hint: use Fourier convolution theorem.)

c. Find the specific expressions for the outputs for f0 = 10/ 2? , 100/ 2? , 1,000/ 2? , and 10,000/ 2? Hz. (You may use a calculator or Matlab for the computation.)
