Can any body explain about
How a discrete signal(Am using an audio file as a signal) can be bandlimited. In my process first audio signal is split to frames containing some samples, Is this called bandlimiting ?
If so it is specified to bandlimit in the range of 300Hz to 2000Hz,
How this can be achieved.
I know that if we do fourier transform we get signals in frequency domain , please tell me how it can be related to my task.
