Plots of Amplitude Response

Input := 

Plot[Amp[w], {w,0,8}]

Output =

Note the peak amplitude in the response which occurs at a frequency of approximately 2.09 radians per second. At this frequency the dynamic system is resonating. This corresponds to tuning in an electrical circuit.. The input to the system is "matched" to the system's own internal properties in a way that produces maximum output. The following two plots show different features of the plot above.

Input := 

Plot[ Amp[w], {w,1.8,2.2}]
