Generate plots for the function in Example 8.1 with sample intervals of 0.5 sec, 1 sec, and 10 sec. Explain the results in light of the sampling theorem. Example 8.1 Sampling Theorem and Aliasing Consider the function FO sin( at)+sin br) Using a trigonometric identity for the sum of two sinusoidal functions, we can rewrite FO as the following product: a+ b If frequencies a and b are close in value, the bracketed term has a very low frequency in...
I wrote a Matlab program for the figure below. When I plot the waves, they look the same. Why do the two waves frequencies look same and How do I avoid it? (I really do need this part of the question answered.) N = 200; % Total number of time domain samples in simulation. Fs = 100 ;% sampling frequency. F1 = 10; % frequency of wave - 1. F2 = 90; % frequency of wave - 2. phi =...
