Abstract: | A Popov-like stability criterion is derived for use in the analysis of a class of time-varying discrete control systems. The class of systems consists of a time-varying gain followed by a causal time-invariant discrete convolution operator. The stability criterion provides a simple graphical means of obtaining stability information which complements the existing information for this class of systems. |
