WebIn the application you specify a block size and sample rate. The low-level driver fills the buffer at the specified sample rate. The application must wait until enough data is acquired to fill one block. Then it can process all the data from the entire block. After that it must wait until the next block of data is full before it can process any ... WebJan 14, 2015 · Let's start with the sample size. The numbers of bins (or "buckets") is equal with half of the samples in your set. For instance, if you have 1024 samples, then you get 512 bins. As simple as that. Now for the sample rate. The maximum frequency is half the sample rate (see Nyquist-Shannon sampling theorem ).
