5th Experiment
The butterworth filter design was done for Low Pass and High Pass. It was done with specific input parameters like As, Ap , Pass Band frequency, Stop Band Frequency and Sampling frequency. H(z) for each were calculated and so was the order of the filter. The theoretical and observed values were compared. Maginitude spectrum and pole zero plot was drawn and it was observed that butterworth filters are monotonic in its pass band and stop band.
Filter is stable when poles are inside unit circle
ReplyDeleteYes
ReplyDeleteOAM and OSM are efficient ways to calculate convolution between very long signal x[n] and finite impulse response h[n].
ReplyDeleteThe spectrum was monotonic.correct observation.
ReplyDeleteWith higher order roll off in transition band becomes steep.
ReplyDeleteResolution becomes better
