Describe in detail the use of the bilinear transformation s → 2 T z − 1 z + 1 for the design of digital filters from analogue filters. Discuss the advantages and disadvantages of the method.

i fully agree with the answers been added by experts..........thanks.

Hamming Window Kaiser Window i)The width of mainlobe in window spectrum is 8π/N ii) The maximum sidelobe magnitude in window spectrum is –41dB. iii) In window spectrum the sidelobe magnitude remains constant. iv) In FIR filter designed using hamming window the minimum stopband attenuation is 44dB. i) The width of mainlobe in window spectrum depends on the values of α & N. ii) The maximum sidelobe magnitude with respect to peak of mainlobe is variable using the parameter α. iii) In window spectrum the sidelobe magnitude decreases with increasing w. iv) In FIR filter designed
