The worksheets that you create typically contain many charts. As the files will be circulated to a wide audience in the organization, you want to add alternative text to charts as you create them. To speed up this process, you decide to have the Alt+Text option as a separate button on the Review Ribbon. Once you have begun the process by going to File, Options, Customize Ribbon, you cannot see Alt Text as a choice in the left-hand list. What steps do you need to take to successfully add Alt+Text to the Review Ribbon? 1 point Click on the “Choose Commands From” drop down. Change the choice from Popular to All. Locate and select Alt+Text and then click the Add button between the two lists to position it on the Review ribbon to the right. Click on the “Choose Commands From” drop down. Change the choice from Popular to Custom Tabs and Groups. Locate Alt+Text and then click the Add button between the two lists to position it on the Review ribbon to the right. Click on the “Choose Commands From” drop down. Change the choice from Popular to All. Locate and select Alt+Text. With the Review Ribbon selected in the list to the right, click on the New Group choice. Type a name and press enter. Click the Add button between the two lists to position Alt+Text in the group.

Text: Sampling of sinusoidal signals (sampling frequency and Nyquist rate) 1. Find the period and time delay in seconds of the following signals with respect to cos(Qot): a. cos(200t+t/4) -> cos(200t+t/4-2) b. sin(2x10t-4r/3) c. ej(400rt-r/6) (tip: find time delays in real and imaginary parts) d. 2cos(103nt+n/4)+sin(103nt+n/4) (tip: using phasor method combining two same frequency sinusoids to form xa(t)=Acos(Qot+)) e. 5cos(103t+t/4)+sin(4x103t+t/4) (tip: This signal has two frequency components. The time delay is different for the different frequency components.) 2. Fourier series of a periodic signal is defined as xa(t) = Σ X ejωkt where ωo is the fundamental frequency of the signal. Find the Fourier series expression of all the signals found in problem 1 via observation using Euler formula. 3. A sampled signal is expressed as x(n) = (t-0.005n)cos(40t): a. What is the sampling frequency? b. How many periods of the continuous-time cosine function are sampled? c. Find the sampled vector x(n) and plot it. 4. Sampling each period of cos(200t+t/4) with 5 samples: a. What is the sampling frequency? b. Is the sampling frequency higher than the Nyquist rate of the signal? Explain. c. Find the expression of x(n) and what is the period, N, in number of samples? How many samples delay compared with cos(Qot)? d. Plot 3 periods of the sampled signals cos(200t+t/4) and cos(200nt) on the same graph in Matlab. 5. Sampling signal 5cos(103nt+t/4)+sin(4x103nt+t/4) with a sampling frequency that is 8 times the Nyquist rate of the signal: a. What is the Nyquist rate of the signal? b. What is the sampling frequency? c. Find the expression of x(n) and what is the number of samples per period, N? d. What are the normalized frequencies of the signal components? e. Plot 3 periods, 3N samples, of the sampled signal in Matlab.
