Matlab - A discrete-time system has the following unit-pulse response

There are two files which both need completed. Please see attached files for full problem description. Please be sure to provide code and plots. Thanks. Lab 2: 1. A discrete-time system has the following unit-pulse response: h[n] = 0.5^n – 0.25^n, for n >= 0 Correspondingly, the following difference equation describes the behavior of the system: y[n+2] – 0.75y[n+1] + 0.125y[n] = 0.25x[n+1] A. Use the MATLAB command conv to calculate the response of the system to a unit step input, x[n]=u[n]. Consider 0 =< n <= 20. Show what you type into the MATLAB command window and submit a plot of the output. Please label the axes. B Use the MAT... click for more

Matlab - Sunspot

Please be sure to enclose all plots and codes on a word document. Thanks Lab 4: Activity 1: Step 1: Download the monthly sunspot data for the 33-year period from January 1875 through December 1907. This will be a total of 396 data points. Go to http://sidc.oma.be/sunspot-data/. Under ASCII files, select monthly and monthly smoothed sunspot number. Save the data to the current directory of your MATLAB work space (denoted at the top when you open MATLAB) as a text file. Open the file by double-clicking and adjust the Notepad window until four columns display. Then delete everything from the top down to where the first 1875 appears. Delete everything from after the last 1907 down to the bot... click for more

Please see attached lab assignment and exel data. On the first problem I am supposed to take the exel spreedsheet data and use it in MATLAB.
