The transfer function that was implemented in this VI is a low pass filter given by + 11 s2 . We can verify that this is true by looking at the graph of the Bode Magnitude plot and Filtered Signal. It is easily seen that any frequency lower that 1 Hz is passed while frequencies higher start to degrade as the frequency increases. Another way to observe the low pass function of this system is to study the Filtered signal graph. As the frequency of the input sin wave is raised it is apparent that the filtered signal is trending towards a single sin wave. When the Frequency of the input sin wave is lower, say at 0.5, the low pass filtering becomes apparent. When the input has a low amplitude, the filtered response starts to climb up in amplitude. Also when the input’s amplitude starts climbing, the filtered signal’s amplitude begins to decrees. The discrete system as seen in the Freq Response graph also is a low pass filter. It is easy
