Question

The dimensonal signal of any two are the same in which​

Answer 1

If a signal depends on only one variable then we call it one dimensional, and if a signal depends on two variable we call it a two dimensional signal.

But when we represent an one dimensional signal, we use two axes(amplitude vs. time). In case of a two dimensional signal, we use two axes (for example, the x axis and the y axis in an image).

How can I understand the difference between a one and two dimensional signal?

No, when you plot a two-dimensional signal, you use three axes: x,y

x,y

, and amplitude. – DumpsterDoofusFeb 10 '14 at 22:18

Basically the dimensional number refers to the number of independent variables (input).

In one dimensional signal

f(t)

f(t)

, the amplitudey=f(t)

y=f(t)

is the dependent variable (output), and there is only one independent variablet

t

.

In two dimensional image

f(x,y)

f(x,y)

, the two independent variables are

x

x

andy

y

, and the dependent variable

f f

is also called intensity. If you want to make it similar with amplitude vs time plot as you do with one dimensional signal, you can plot a intensity vs x vs y scattered dots with three axis as well.
