Erratum to The PLSI Method of Stabilizing Two-Dimensional Nonsymmetric Half-Plane Recursive Digital Filters

The Original Article was published on 18 August 2003

Erratum

The authors would like to bring to the kind attention of the readers the following corrections to the paper [1].

Equation (23) in page number 917 is as follows:

(1)

It should be noted that in (23) and all equations in the rest of the paper that contain the term , this term is the constant term of the polynomial , which is the stable version of the 2D PLSI polynomial . Since we have assumed that 's are the coefficients of the 2D PLSI polynomial, the coefficients of the polynomial are 's.

Equation (46) in page number 920 is as follows:

(2)

This equation may be corrected as follows:

(3)
