Neil S.,
It’s I who must say ‘thanks’, not you so Thanks 🙂 I’m not interest at all in the indexs, it was just to verify the acquisition synchronism. I’m working with sine wave signals, so basically I only need one period to work but with more samples more precise is the acquisition.Acquiring the signals and just measure frequency and amplitude they look correct. But don’t tell me about if the synchronism is correct. And when multiplying two sine signals they must be. I’m using electric circuit in a breadboard to generate my sine signals, and yes my application will measure a sine wave.
