#### Problem 1 Write MATLAB Program to compute and plot the frequency response of a causal LTI discrete-time system with a transfer function given by for 0 . What type of filter does it represent? H(z) 0.15(1 z2 ) 10.5z1 0.7z2 Problem 2 Repeat Problem 2 for the following transfer function: H(z) 0.15(1 z2 ) 0.70.5z1 z2 What is the difference between the two filters in problem 1 and problem2, respectively? Which one will you choose for filtering and why? Problem 3 1. Find this filter impulse response. 2. Find the output of the filter when the input x[n] using linear convolution. 3. Find the filter frequency response using a. MATLAB (freqz) and b. MATLAB (FFT). 4. What was the effect of the filter on the signal? Explain! 5. Is the frequency response of the filter consistent with the result obtained in part 2? Explain. 6. Find the filter frequency response by hand. Is this result consistent with the one obtained in part 3? 7. What type of a filter is this one (LP, BP, or HP). 8. Repeat all parts from 1 to 7 for the following causal FIR filter y[n] = 0.5 x[n] -0.5 x[n-1] Given the following signal x[n]= [20 18 22 17 23 19 21 17 18 14 16 12 14 11 12 9 10 7 8 4 7 ] and a causal FIR filter characterized by the following difference equation: y[n] = 0.5 x[n] + 0.5 x[n-1] Ikhlas Abdel-Qader Page 1 of 1 5/14/2020

#### 1. A conducting bar is put in a constant magnetic field B = 0.1T. The circuit resistance is R =10Ω. The bar width is 20cm. The mass of the bar is m = 1kg. The circuit and the metal bar are on a flat horizontal surface. If the bar has an initial speed (t = 0) of V0 = 4m/s, determine: (a) The current generated in the bar at t = 0; (b) The force experienced by the conducting bar at t = 0; (c) The speed of the bar at time t = 10s;

#### 6. (20 points) X (t) is a wide sense stationary process with zero mean and autocorrelation RX (t) = e− a | t | with a = p. We observe Y (t) = X (t) + N (t) where N (t) is a white Gaussian noise process with N0 = 10−5 . X (t) and N (t) are independent. (a) What is the transfer function of the optimum ﬁlter for estimat- ing X (t) given Y (t)? (b) What is the mean square error of the optimum ﬁlter estimate?
