If the sine frequency is known, perhaps you could use a goertzel filter and compare a average signal power calculation to measure the power of the error signal.
That doesn't identify the nature of the error, but strikes me as an interesting approach. _spencer On Wed, Jan 10, 2018 at 9:23 AM, Eric Brombaugh <ebrombau...@cox.net> wrote: > Maybe try locking a PLL to the sinewave to get the expected frequency and > phase, then look for differences between them? > > Eric > > > On 01/10/2018 09:08 AM, Benny Alexandar wrote: > >> Hi, >> >> I want to do some time domain analysis on a sine wave signal which is >> continuously streaming. >> My objective is to detect any discontinuities such as audio gap, fading, >> phase discontinuity etc. >> >> Any algorithms available on time domain other than doing FFT based >> approach ? >> >> -ben >> >> >> _______________________________________________ >> dupswapdrop: music-dsp mailing list >> music-dsp@music.columbia.edu >> https://lists.columbia.edu/mailman/listinfo/music-dsp >> >> > _______________________________________________ > dupswapdrop: music-dsp mailing list > music-dsp@music.columbia.edu > https://lists.columbia.edu/mailman/listinfo/music-dsp > >
