Hi guys

Currently I'm investigating some code about ASK, PSK and FSK.

I saw code like this ".*" (dot and multiplication symbol). My question is this:

Assume A is a scalar. Then, are

Xc=A.*sin(2*pi*fc*t) and

Xc=A*sin(2*pi*fc*t)

the same thing? If not somebody please explain to me the difference(s) between them.

There is no difference in Xc if A is a scalar.
