Make sure each question is clearly shown in your submission. All answers must be typed and plots must be done by computer. Don’t forget the cover sheet! Download and umzip ConvolutionGUI Matlab . Practice: Make sure you understand Example 3.5 on page 102; 3rd Edition. A) Convolution Integral (30 points)Download the ConvolutionGUI program. Run the program and make sure you understandhow it operates. Show what happens when you apply convolution integral to the following two signals and in each case show the result: a) Two Rectangular Pulses. b) A Rectangular Pulse and a BiPhasic (positive and negative) Pulse c) A Rectangular Pulse and an Exponential d) Two ExponentialsB) Convolution Integral (40 points)Consider the system described by the differential equation:Assume we use convolution to find the zero input response of this system. Thus, y(t)=h(t), when input is zero. a) What is the impulse response, h(t) for this system? Assuming the input is defined as follow: b1) What type of electrical circuit does this system represent? b2)Draw the appropriate circuit with correct component values. B3)What does f(t) represent? c) Using MATLAB subplot, draw h(t) and f(t). Show the code. d) Calculate y(t) using convolution integral. Show all the steps. Hint: the input function has three distinct regions t<0, 0<t<1 and 1<t.e) Write a MATLAB code to evaluate y(t). Show your code. f) Plot the y(t) using MATLAB. g) Using the ConvolutionGUI program, depicted y(t) graphically for the following: t=-0.2, t=0.5, and t=1.2. On each plot clearly show the value of t. h) Show the plot generated from ConvolutionGUI program and the plot you created usingyour Matlab code side-by-side. Are they the same? Show one “t” value on both graphs to indicate the results are almost identical. C) More on Convolution Integral (30 points)Using the ConvolutionGUI answer the following questions: (you can also use http://www.jhu.edu/~signals/convolve/ to get more information). Hint: In order to really understand these problems you must practice Chapter 3 problems 1-14. In each case verify your answer and clearly answer
