Dear List:
I have a doubt in filter implementation! I wish to include the effect of quantization after multiplication with the filter coefficients. Eg. I need, y[n] = Q(x[n] b0) + Q(x[n -1] b1) -Q(y[n -1] a1) ; where Q(.) is a quantization operator. How do I make it work like the MATLAB function filter.m? i.e. I need the filter outputs as well as the states. I will be glad to receive your help/hints/tips. Regards, Arijit |
