Trigonometry terminology

I am not a super expert on this but I think you just described it the way it is described. I know of no specific word for it. I like to think my vocabulary is pretty good but I could be wrong.

You might try putting your description into a search engine and see what it says about it.

Synchronous?

I used to know the terms for this sort of thing, but can't remember. There are isochronous & isochronal.

Same frequency, different amplitude and phase, is the best I can do :^)

George H.

How about locked in frequency (doesn't say anything about amplitude and phase).

Those types of signals are called coherent. It is a very broad area of study, but, when you say coherent sine waves, the people who know the field will understand it to mean exactly what you describe.

Best suggestion yet

Correlated is not correct. A since wave and cosine wave are totally uncorrelated.

Phase locked?

You could say two sinusoidal waves constructed from the same sin/cos basis pair.

In tune.

So the cross-correlation function is everywhere zero?

Yes indeed. My _IEEE Dictionary_ says it this way:

coherent (1) (fiber optics). Characterized by a fixed phase relationship between points on an electromagnetic wave. Note: A truly monochromatic wave would be perfectly coherent at all points in space. In practice, however, the region of high coherence may extend only a finite distance.

Thank you, 73,

Two sine waves will differ only in phase and amplitude if one is *derived* from the other - eg the input and output of a filter or amplifier.

Or, although coming from independent sources, one is phase locked to the other with some fixed phase difference.

You do come up with some whacky absurdities.

Having a nice troll ??

Synchronous, or synchronized, means to me that the phase relationship is invariant, or equivalently that the cross-correlation function is constant.

They are both sine waves with the same frequency. (that is it)

Amplitude and phase of each waveform is unspecified.

Or do you want to specify their amplitude ratio and phase?

Unison is a musical term or that.

Ummm- could be any echo or a comparison to be made from some other channel transmission as with a lock-in amplifier.

I see you are suffering from "echo" and trolling.
