Then, determine the transfer function of the BIBO stable analog low pass filter, Ha ( s ). Specifically, determine the type and order of the filter you would need. 7c) Step #3: Design an analog lowpass filter that will satisfy the requirements. Do not forget to show the specifications of the corresponding analog lowpass filter. Use Bilinear Transformation with T = 2 for simplicity, and perform the necessary pre-warping. 7b) Step #2: Derive specifications of an appropriate analog low pass filter. Do not forget to show the specifications of the corresponding digital lowpass filter. Many choices are possible, So, arbitrarily, let us assume a cutoff frequency, wp = 0.1 π, for such a filter, and derive a suitable lowpass to bandpass digital transformation and pre-warp the frequency axis appropriately. 7a) Step #1: We will derive specifications of an appropriate digital low pass filter. This problem will walk you through the steps of such a design procedure. The goal is to use lowpass to bandpass digital transformations and bilinear transformation to design the filter. Design a digital bandpass filter with the following specifications: wp1 = 0.46 π, wp2 = 0.66 π, ws 1 = 0.31 π and ws 2 = 0.76 π, passband ripple 1 db and stop band attenuation of 40 db.
