Analytical:

$$\frac{\partial u}{\partial t}-c\frac{\partial u}{\partial x}$$

solution: $$u(t,x)=f(x-ct)$$

-----------------

Euler forward: Only stable when with upstream space differencing. Introduces a strong damping. The CFL criterion must be also fulfilled.

Leap-frog scheme: conditionally stable with the CFL criterion.

Fazit: I would use leapfrog since it has a higher order of accuracy than the others.
