The aim which has to be achieved and the contents of this experiments are as follows :
To design digital filter using frequency sampling method
We have to accept two inputs, one is for LPF and another is for HPF. After which we design a linear phaase as well as non linear FIR filter and lately plot a magnitude spectrum and phase spectrum and on verifying Ap and As in spectrum we jump to conclusions. Also we need to note that ripples in the stop band are obtained of decreasing amplitude. The phase plot is linear and similar to both Lpf and hpf if order of two filters is same since phase is linear the output will not be distorted.

Lobes are present in the magnitude spectrum in stop band for both cases.
ReplyDeleteno. lobes are related to order of the filter
DeleteYes in both cases
ReplyDeleteYes in both cases
ReplyDeleteHas any filter design been tested by any simulator?
ReplyDeleteThank you for your most valued and notable question..
ReplyDeleteWe have designed and simulated it in scilab as stated
And it can be tested simulated using Matlab simulink

Which Design method have you implemented for the FIR filter?
ReplyDeleteWd (w) is converted to Wd (k) by substituting w=2e^j2πk/n
