8. Legend: Add a legend to your plot with the Matlab command legend's(t)', 'sl(t): -pi/2 phase shift', 's2(t): pi/2 phase shift') 9. Label Axes: Now label your plot axes. The x-axis is labeled using the command xlabel ( 'Phase in Radians') and the y-axis labeled by the command ylabel ('Sinusoid') 10. Title: Add a title to your plot with the command title ('Comparison of Phase-Shifted Sinusoids'). 11. Print Plot: Print or save your plot to print out later. Include the printout of your plot in your lab report 12. Time-Shifting: (A). Generate a time-shifted version of s(t) as s3(t) = s(t-ts), where t3 = T0/4. Show that s3(t) = 81(t). This means that a time shift of t3 = T0/4 is equivalent to a phase shift of-/2. Save your commands that you used to show that s3(t) s1 (t) in your lab report. Do NOT print out the elements of either 83(t) or s1 (t). You do not need to plot s1(t) and s3(t) to prove they are identical. However, that is one way of many to do so. 13. Time-Shifting: (B). Generate a time-shifted version of s(t) as s4(t)s(t t4), where t4-To/4. Show that 84(t) = 82(t); in other words, a time shift of t4 =-70/4 is equivalent to a phase shift of /2. Save your commands that you used to show that s4(t) = s2(t) in your lab report. Do NOT print out the elements of either s4(t) or s2(t) 14. Conclusions: What are your conclusions about time shifting and phase shifting? Did you find that plotting a phase-shifted waveform helped you to better understand the effect of phase shifting on a sinusoid? More generally, what are your conclusions, based on this lab, about the suitability of Matlab for representing and displaying signals? 8.
