1. What are the three frequencies shown in the spectrum of the non-filtered signal?
2. What is the difference in the filtered signals spectrum compared to the nonfiltered signals spectrum for the two different filters?
3. When a signal is put through a filter, how is the signal affected?
4. A signal contains a mixture 30 , 100 and 240 Hz Sine waves and also contains wideband noise whose spectrum is from 500 Hz up to a 1000 Hz. Describe a filtering technique that can be used to cleanly separate 30, 100 and 240 Hz from each other and also from the wide band noise.
