Q9b Design a digital IIR Filter using BLT with a cutoff frequency of 15Hz & sampling rate of 90Hz.

The video explains the design of a normalized lowpass filter with a cutoff frequency of 1 rad/sec is given as: H_P (S)=1/(s+1), using BLT to design a corresponding digital IIR lowpass filter with a cutoff frequency of 15Hz and a sampling rate of 90Hz. #BLT #Bilinear Transformation #Digital IIR Filter #DSP #Solutions to DSP Model Question Paper #2022 Scheme #VTU
