    Thank you, DaveE.

    Transfer function with initial conditions (DE)

    Yes, I see. I think I did intend to put an input in there. So let me re-formulate my equation as: y''(t)+y'(t)+y(t)+C = u(t) where u(t) is an input. If I take the laplace of both sides I get s2Y(s)+sY(s)+Y(s)+(C/s) = U(s). But now I have a term on the left side that doesn't have Y(s) in it, so I...

    Transfer function with initial conditions (DE)

    I think because it can be re-written as y''(t)+y'(t)+y(t)+y(0) = 0, where y(0) evaluates to nonzero.

    No, not for schoolwork. I'm getting ahead at my workplace and trying some self-learning.

    Transfer function with initial conditions (DE)

    I have a differential equation of the form y''(t)+y'(t)+y(t)+C = 0. I think this implies that there are non-zero initial conditions. Is it possible to write a transfer function for this system? This post...
