fundamental period
have a doubt reg checking DT periodic sequence:
x[n]=cos(pi* ^2 / 8 )
it is periodic ofcourse, but in the solution manual its fundamental period is mentioned as 8.
but i got fundamental period=N=(2*pi/ omega )
in this case, N= (2*pi / (pi/8) ) = 16.
does anybody know about how they getting N to be 8 ????
