The book I am using is "Digital Signal Processing" (Third Edition) by Prokis and Manolakis. It is question 2-45 on page 144. Consider the system described by the difference equation: y(n)=a*y(n-1)+b*x(n) determine b in terms of a so that THE SUMMATION OF h(n)=1 The limits of the summation are

If X is a nonempty subset of a group G, let <X>={x1^(k1),x2^(k2)...xm^(km)|m>=1, xiEX and kiEZ for each i}. a) show that <X> is a subgroup of G that contains x. b) show that <X>C=H for every subgroup H such that XC=H. Thus <X> is the smallest subgroup of G that contains X, and is called the subgroup generated by X. note:
