Question

For Both Figures:

Type I FIR Filter, Zero Phase Response Magnitude Response 0.35 0. 30 - Real Imaginary 0.25 0.2 0.15 0. 51 1 2 2.5 3 3.5 Figure A 0.1 Phase Response 0.05 Wrapped Unwrapped -0.05 -0.1 - 5 10 15 20 25 0. 51 1.5 2 2.5 3 3.5 Type I FIR Filter, M=5 0.35 Magnitude Response Real Imaginary 0.3 - 0.25 0.5 0.2 0.15 Figure 0 0.5 1 2 2.5 3 3.5 0.1 B Phase Response 0.05 Wrapped Unwrapped ooooooooooooooooooooooo -0.05 -0.1 0 5 10 15 20 -54 0 0.5 1 1.5 2 2.5 3 3.5

Is h[n] symmetrical or asymmetrical?

How is the magnitude response?

Is the phase response linear? Why?

My current answer is:

For Figure A: symmetrical, not sure about mag response, linear phase response

For Figure B: asymmetrical, not sure about mag response, non-linear phase response because of the slight delay in the wrapped phase response?  

A full explanation for the magnitude and phase response, please.

Answer 1

For Figure A

h(n) is Symmetric, Magnitude response is asymmetric, phase response is not linear.

For Figure B

h(n) is asymmetric, magnitude response is asymmetric, phase response is not linear.

PAGE-OL a. For both figures Is hm) symmetrical or asymmetrical ? How is the magnitude eesponee? Is the phau responu linear ? why? the. While dealing with signals we can come across signale which care symmetric or Unsymmetric / Asymmetrical. Three types of Symmetry cure there – (2) Even Symmetry (6) Odd symmetry (c) Half wave lymmetry A waveform which dount fall in either of these are called Qummitauic. What in linear? A waveform that strictly followe Y= I mic lineau. Otherwise non-linear- is said to be 4=mol Y=-mid I Linear For Fique - A h(n) in Symmetric. Your anuver it right. It is a type of Even Symmetry. Je jou see the magnitude Responses the magnitude in the beginning unculan attaire maamun and then con limvovely decays, such decaying nature cannot poses any Symmetry. Thus Magnetice Ruponu in Asymmetric

PAGE-02 doesn't follow Similarly, phase reeponie ui Non-linear at it Y = tma. Fвч Горна - 3 hlm) ie Symmetric as it doen't fall in any lype of Symmetry Magnitude Reefonu ii decaying in nature, so it is Aymmetric Phase veehonse in Non-linear because it does not follow Y= Imac. I NOTE: Furou a follow response to be liniar it must vetrictly Y= Imol.
