The dominant frequencies present in the train whistle sound that was examined in the prelab are 1107Hz,1393Hz, and 1838Hz. 1. Let us say that we create a signal y2 by picking out every second sample of y. We also create a signal y3 by picking out every third sample of y. Note: This can be done in Matlab using the command: y2=y(1:2:end) What is the effective sampling rate Fs2 for the signal y 2 ? What is the effective sampling rate Fs3 for the signal y3? Do any of the 1107Hz,1393Hz, and 1838Hz components experience aliasing at the sampling rate Fs2 ? Explain. Do any of the 1107Hz,1393Hz, and 1838Hz components experience aliasing at the sampling rate Fs3 ? Explain. Determine the analog frequencies that each of these components gets aliased onto. Use the relationship F=fFs for this step. Ensure that f is in the fundamental range 0.5
