The applications of the wall attachment fluidic device have become so wide that the establishment of a method for circuit analysis is urgently needed. The dynamic analysis of the circuit with capacitance can hardly be treated graphically and, moreover, in a large amplitude operation, the nonlinearity caused by switching elements prevents us analizing with a linear equivalent circuit such as seen in an analog circuit. Here, an attempt is made to apply the method of parameter representation, which was previously reported by the author, to the dynamic circuit analysis.
First, the element loaded with volume is replaced by a nonlinear resistance, connected by the capacitance. Then its step response is analyzed and expressed by the time constant defined here. Further, an attempt is made to represent in the same way the step response of the circuit in which the input resistance of the next stage is connected parallel to the capacitance.
Now the method of step-response represantation is applied to the capacitance-feedback oscillator, and its characteristics are analyzed. The results become fairly acceptable by taking the dead time, such as the switching time, into consideration. This method might be applicable to the analysis of other systems like a fluidic controller, etc.
