HOMEWORK #5 1. Write a MATLAB program to demonstrate aliasing and A/D resolution for a sine wave. The program should do the following: Prompt the user for input waveform and A/D characteristics (e.g., amplitude, dc offset, and frequency of sine wave, full
HOMEWORK #4 1. Create a MATLAB function to calculate the probability density function of a variable. Use the first few lines below as a guide. Then test your function using the output from the `hist' MATLAB function, suitably scaled, on sample data. Plot
HOMEWORK #3 1. Plot the impulse response function h ( t ) vs. n t for each of the pole locations shown below in the complex plane. Make one plot for each colored line, and identify the line as having a constant damping ratio, time constant, or oscillation
HOMEWORK #2 1. In the Matlab script "ensemble_vs_time_avg.m" discussed in class, is the ensemble average technique using the sampling rate ( dt = 1 8192 sec. ) and number of samples in each block (8192) always effective in eliminating the random noise com
