Find the Fourier transform specified in part (a) and then use it to answer parn
(b).
(a) Find the Fourier transform of
e-" sin pt t>0,
t< 0,
f(7. p.t)
where y (> 0) and p are constant parameters.
(b) The current I(t) flowing through a certain system is related to the applied
voltage V(t) by the equation
I(t) =K(t-u)V(u) du,
where
K(t) = af(y1, P1, 7) + azf(72, P2, T).
The function f(y, p, t) is as given in (a) and all the a, n (> 0) and p, are fixed
parameters. By considering the Fourier transform of I (t), find the relationship
that must hold between a, and az if the total net charge Q passed through
the system (over a very long time) is to be zero for an arbitrary applied
voltage.
