A SIMPLE EXAMPLE Since the approximate formulae derived in Section IV are somewhatunfamiliar it seems proper to consider in a rather detailed manner asimple example.* Consider the system of Fig. 5. Assume that the current source appliesa constant current to the system and assume that the steady state isreached. For simplicity let hR = E. The steady-state behavior of the voltages ^^2(0 and e:i{t) = €4(1) is * In addition, the limiting case of the sampling rate —> 0, is treatedin II. SWITCHED XETWORK FOK TIME MULTIPLEX SYSTEMS 1415.
