1.2. Obtaining a computer-generated plot of a continuous-time signal requires some care in choosing the time increment (the spacing between points).As mentioned in Section 1.1, too large of an increment will cause a jagged plot. Moreover, a very large time increment may introduce a phenomenon known as aliasing, which distorts the information given in the signal.(Aliasing is covered in greater detail in Chapter 5.) To avoid aliasing when defining a computer-generated sinusoid such as choose A rule of thumb in the case of a decaying sinusoid such as is to choose (Choosing even smaller values of creates smoother plots.) (a) Compute the maximum time increment for plotting in MATLAB. Verify your result by plotting x(t) for to with the following time increments: Note the apparent change in frequency in the plot due to the aliasing effect for How do you expect your plot to appear when Verify your result. (b) Compute the maximum time increment for plotting Verify your result by plotting x(t) for to with 0.5,1.5,and 2 sec.
