A signal whose sampling rate is 22050 Hz but what will happen if we sample it at 32KHz,44.1KHz and 48 KHz?

Is it because of oversampling may occur or it prevents aliasing?Please do suggest me the reason behind it??Thanks in advance.....

You mean resample a previously collected datastream or actually sample the analog input at higher sampling rates?

I mean to say that actually sampling the analog input at higher sampling rates?

If you resampled your signal at a higher rate, you would likely not have any detectable difference in the output. The hardware in most ADCs incorporates a hardware anti-aliasing filter, so any frequencies above 11025 Hz should not be present in the original sampled signal. The only significant effect would be to lengthen the signal vector and the file size.
