Hi all, this is my first post so please bear with me - anyadvice/support would be warmly welcomed. I have been doing some work on asimple RLC electronic circuit whose transfer function follows the standardsecond order transfer function.

The forcing function (input) is a periodic square wavefunction and I am trying to write an equation for the output - time based.

Please find 2 documents attached in which I have tried todevelop equations for the output using 2 different methods. The first one is usingcomplementary function and particular integrals (which I do not like). Thesecond one uses Laplace transforms. I have found a time based equation but wheni input times i do not think i am getting the correct output values. Cansomeone please have a look -

particularly the Laplace pdf.

Many thanks, derek
