TRADE-OFFS IN LINEAR FILTER DESIGN

This paper examines trade-offs arising in the design of show that ther e exist linear filters. These fundmental limits on filter performance- limits that are independent of the method of design. These limits may be employed to determine a priori whether desired design specification s are achievable. Analogous constraints are well known in the area of feedback control systems, but, to the best of our knowledge, they have not previously articulated for the filtering problem.
