i don't understand ur question

sorry for that

Answer 2

If I understand correctly, you are describing signal resampling which implies at least two answers.

Sample-rate conversion case

Given that a sampling frequency of R has a nyquist frequency of R/2, and the signal:

x ′ (t) = x(2t)

has an implied sampling rate of R/2, the nyquist frequency would be R/4.

Pitch-scaling case

Instead, if the sampling frequency R is held constant, the nyquist frequency will remain R/2. However, the frequency content of the signal x ′ (t) would be shifted upwards by 2.

For either use case, resampling without filtering is crude and can introduce aliased frequency content in the resulting signal. There are many well-known sample-rate conversion algorithms that explore this problem space effectively and minimize artifacts.

Hope it will helps for.
