Differential equation to transfer function
The transfer function of a system G(s) is a complex function that describes system dynamics in s-domains opposed t the differential equations that describe system dynamics in time domain. The transfer function is independent of the input to the system and does not provide any information concerning the internal structure of the system. Jan 14, 2023 · The transfer function of this system is the linear summation of all transfer functions excited by various inputs that contribute to the desired output. For instance, if inputs x 1 ( t ) and x 2 ( t ) directly influence the output y ( t ), respectively, through transfer functions h 1 ( t ) and h 2 ( t ), the output is therefore obtained as A transformer’s function is to maintain a current of electricity by transferring energy between two or more circuits. This is accomplished through a process known as electromagnetic induction.
