Two dimensional IIR and FIR digital notch filter design

In this paper, the two dimensional (2D) digital notch filter design problem is investigated. First, we develop a simple algebraic method for 2D IIR notch filter design. This approach not only has closed-form transfer function but also satisfies bounded input bunded output ( ~ 1 ~ 0 ) stability condition. Next, we use Lagrange multiplier method to design 2D… CONTINUE READING
