Band pass
Instant
Autocorrelation
Homodyne
Phase accumulation
Hilbert
Dual Differentiator

this is brand new to Retail

  
I was only pointing to the period of dominant cycle mentioned above... Not in general about DC things. The one I mentioned uses Hilbert. And this, If I'm not mistaken, is one based on the dominant cycle period mentioned in Ehlers' book "...rocket science..." thingy.
