Thanks Born2bwire. If the ramp up is almost instantaneous, then just the front of the wave will be moving at a particular velocity. At a particular x, at one discrete time y=0 and the next discrete time y=1
If it helps, I have attached a graph of the progressing wave.
Hi
I have a case where a wave with an amplitute 'A' progresses with a particular velocity 'v'. The wave is such that the amplitude at x=0 increases to particular value and stays there for the entire time
some thing like below.
at time(t)=0
x(position) =...
