Electronic – Time Reversal Operation for discrete time signals

discrete fourier transformlaplace transformsignalsignal processingsignal-theory

For a discrete time unit step signal 'u(n)' , if time reversal operation is performed then it becomes 'u(-n-1)'.
Is it true for ANY discrete time signal 'x(n)' such that time reversal operation makes it 'x(-n-1)'….?

By definition, if you replace n with k-n, then it's time reversed.

What value you use for k seems to me to be a matter of convention. It affects the time shift of the signal. K will depend on what time datum you reverse it about.
