Create a sinusoid with "frequency" 0.1, "amplitude" 3.75, and "pulse width" 40. When all of the parameters have been entered, press the [Update] button to update the signal preview. Remember that whenever changes are made to this box, the [Update] button must be pressed in order for the changes to take effect. On the right, you can preview the signal. Count the number of samples within a period. How many samples do you have within a period? (ans: 20 samples). Step 1.2: Create a sinusoid with "frequency" , "amplitude" 3.75, "pulse width" 40 (remember to press [Update] for changes to take place). What happens? (ans: no signal due to aliasing, i.e., the signal has been sampled precisely at the zero crossings). Step 1.3: Create a sinusoid with "frequency" 1.3, "amplitude" 3.75, "pulse width" 40. What happens? Count the number of samples within a period. (ans: we have aliasing again; sinusoidal frequencies must be chosen to be smaller than to avoid aliasing)
