well, I'll jump straight into the theory.
Wave equation is a ii order hyperbolic PDE
by solving it with the principles of superposition( Fourier concepts )
we can take the solution of the wave equation as
y =3D A cos( 2 * pi * f + phi )
I think this is the back bone of the most of the electronic stuff.
From a given crystal we can produce only frequency, but not amplitude.
my doubts was,
(1) how amplitude was produced depending our requirements ? what is logic behind that ?
