Abstract :
In this paper, 2-D transfer functions, whose magnitude characteristics can be varied, have been obtained as a cascade connection of several first-order sections (the order of each variable is unity). New stability conditions corresponding to the various polynomial decompositions have been obtained. A general signal-flow graph is given in which the parameter to be varied is contained in the feedback loop
