Abstract :
An approach in the design of 2D extremely narrow bandstop FIR filters is presented. The completely analytical design method is based on the 1D optimal bandstop FIR filters. The 1D FIR optimal bandstop filters are based on Zolotarev polynomial. Closed form formulas for the design of the filters are presented. One example demonstrates the design procedure. One application of the 2D narrow bandstop FIR filter for image enhancement is presented.
