Question

Task 4. Show analytically that the frequency responses (FRs) of MA2 and FD2 are, respectively and provide your calculations in the Report. For both filters, plot the magnitudes of the FRs. i.e.. HMA2(ejn)l and [HFD2(eJN)| versus Ω For both filters, plot the gain functions (in dB), ie.. ĢMA2(Q) = 20 logiolHMA2(e, and ĢFD2(Ω) [0, π]. With the help of these plots, try to explain better your results from Tasks 2 and 3. 20 logo HFD2(en) versus Ω e 0, π] and determine (approximately) the 3-dB cutoff frequencies from the graphs

E) )슬 1HnA] 3 x -J느 か2 (e- ←下 F02 ) 스DN

results are not explained as I dont have information of task 2 and 3

The         w Vs G_MA2 plot is

50 100 150 200 250 300 350 0.5 2.5 3.5

From the graph the cut off frequecny is frequency at which G is -3db -> w_cutoff = pi/2

The         w Vs G_FD2 plot is

10 20 25 30 35 3.5 2.5 0.5

From the graph the cut off frequecny is frequency at which G is -3db -> w_cutoff = pi/2
