What is resampling and how to resample a signal in ASI Datalab?


Resampling function is used when you want either more no of samples often called up-sampling or less no of samples called down-sampling in the signal than the current. Resampling changes the sampling rate (Samples / Sec) of a signal and total no of point keeping the total duration of data same.

Usually, the sampling rate is kept higher during data acquisition, but for analysis, it may not require. For many analyses down sampling is required. Up sampling is not advisable as every data acquisition system will have antialiasing lowpass filter which will set based on sampling rate setting during acquisition.
