In this work, an attempt has been made to find out the steady state solution of R-L-C circuit for sinusoidal input using a state-of-the-art sample shifting technique (SST) with lesser computational burden in discrete time domain. The basic integro-differential equations involved in different R-L-C circuits have been solved with the above SST. The samples of the output current waveform are evaluated for each of the circuits from the samples of input voltage and the values of the circuit parameters. The samples of current waveform are also evaluated using conventional technique for the solution of current signal under steady state. A pretty good matching of the samples of output current in MATLAB simulation for both the techniques justifies this proposed SST. Microcontrollerbased experimental validation of the method is also discussed.
