Abstract :
The paper presents criteria for robust stability of 2-D recursive digital systems under finite wordlength implementations. Based on the criteria, the stabilities of digital systems under various complex nonlinear cases can be analysed and tested. The stable work regions of the systems´ coefficients also can be found. The test and analysis procedure is simpler than those of Bauer and Jury (1988) and Basu (1990), especially for high order 2-D digital systems.<>
