In this problem, you will simulate an analog noisy periodic signal, sample the signal and convert it to a digital signal, and write a function to detect the frequency of the original signal. You MUST attach all your codes with your report. (a) [15 points] Examine the file "Prob_1a. m". Write the function "fn_updateArray(newValue)". This function will save "newValue" at the end of the array (called "arrayWithLatestValues") containing the latest sampled values. Every time a new value is read, the older values will be shifted to the left and the oldest value will be discarded. Run the program a few times and include screenshots of the command window in your report.

Which of the following statements best describes it careers?

When you type the pwd command, you notice that your current location on the linux filesystem is the /usr/local directory. answer the following questions, assuming that your current directory is /usr/local for each question. a. which command could you use to change to the /usr directory using an absolute pathname? b. which command could you use to change to the /usr directory using a relative pathname? c. which command could you use to change to the /usr/local/share/info directory using an absolute pathname? d. which command could you use to change to the /usr/local/share/info directory using a relative pathname? e. which command could you use to change to the /etc directory using an absolute pathname? f. which command could you use to change to the /etc directory using a relative pathname?

Suppose s, t, and w are strings that have already been created inside main. write a statement or statements, to be added to main, that will determine if the lengths of the three strings are in order by length, smallest to largest. that is, your code should determine if s is strictly shorter than t, and if t is strictly shorter than w. if these conditions hold your code should print (the boolean value) true. if not, your code should print false. (strictly means: no ties) example: if s, t, and w are "cat", "hats", and "skies" your code should print true - their lengths are 3-4-5; but if s, t, and w are "cats" "shirt", and "trust", then print false - their lengths are 4-5-5 enter your code in the box below
