I was reading digital signal processing. In topic Discrete Fourier Transform, circular symmetry it is said that circular advance is obtained by shifting x(n) in clockwise direction. i.e. to obtain x(n+k) Shift sequence x(n) in CW direction by k samples.
my question is would it same for x(-n+k)?
circular fold x(n) to obtain x(-n) and shift sequence x(-n) in CW direction by k samples. am i right?
