I need to design a number of digital IIR filters based upon transfer functions given in the s-domain. I have applied the bilinear transform to give the transfer functions in the Z-domain, however I need to expand and simplify the equations to place them in the form below:
Once the equations are in the above form I can get the IIR filter coefficients and implement them into my filters, however I'm not quite sure how to go about it. Would anybody like to take a crack for me?
The three equations are as follows;
An example is given below;
Any help would be very much appreciated!
