What is the purpose of Resampling if it doesn't change the original bandwith of the signal? I have a low sampled analog signal, could resampling change the bandwidth of the original low sampled data? I thought so but any help will be apprieciated

Resampling will not change the bandwidth of the original signal, it allows to have less samples to be treated, which means less memory to use, and faster computational.
