Using Tsypkin's Approach for the Study of a Class of Mixed-Signal Nonlinear Systems

An extension of Tsypkin's approach is proposed, in order to determine the values of the oscillation frequencies of mixed-signal nonlinear systems consisting of one possibly nonideal relay, one discrete-time block with a zeroth-order hold, and one continuous-time block. Several methods for determining the shape of the complex oscillations in some situations are then proposed and discussed.
