Re: A Question About A Simple LRC circuit



Hi Robert-
A delta function is the derivative of a step function. To
mathematicians it does not qualify as a "function". The literature
on the subject is found under the heading "generalized functions".
Regards,
Jack

Hi John I must confess I don't have a clue what a delta function is. I went
to the GIF and I saw what looks like a quarter wave damped sine wave which
started some time after time zero. Perhaps I know what it is under a
different name. Could you flesh this out a little? It sounds intriguing.
