However square wave is still considered as the DT signal.....
actually U are refferring to pulse digital signal which contains zero and one(ON or OFF state)
(instead of real values --- CT signal )
Whereas CT square signal contains real values with respect to time.
here time as well amplitude is continous (i.e., infinite finite values say if amplitude varies from -5v to 5v then within that amplitude one can split up the amitude into infinite range values i.e, -5v, -4.999999999v, -4.999999998v and so on)
thats the difference.
Hope it helps U a little bit.
Happy learning.
