signals...help needed
hi,
can anyone tell me why a discrete time signal x(n-k) where k>0 is shifted right along the X-axis(the time domain) and x(n+k) is shifted left. should'nt it be the reverse? this is for the graphical notation. but for the notation x(n)={...,0,3,2,1,0,1,2,3,0,...}
we go left for x(n-k) and go right for x(n+k) which is past samples and future samples respectively. the graphical and short hand notations are really contradictory to me. so pleasezzz help me
