According to mabat, you can calculate amplitude from phase
Maybe using the above two waves he can give an example
Since there amplitudes are different, youd think the phase would be different, if phase can truly point to amplitude

I talked about complex frequency response, obviously ("amplitude" and "phase").
What you show is a function of time, not frequency.
What you show is a function of time, not frequency.
When you hear group delay distortion..you are hearing a distortion to the start up transient.
Thats probably the point I'd make if I had one. This is a distortion to the amplitude domain...phase is separate.

There's no "amplitude domain". It's the time domain. But yes, phase distortion in frequency domain (i.e. any deviation from linear) can lead to a transient distortion in the time domain. There's no mystery about it.

There is absolutely an amplitude domain....
With signal you have frequency, phase, and amplitude
We can adjust either separately

OK, now I can see where all your confusion comes from. But I don't know how to remedy this.

Let's pretend that we have three different signals in this picture, we should be able to use this picture to explain the concepts properly
Under my current thinking amplitude is not the same but phase and frequency are not.
If I get what youve been trying to say... these three signals have the same frequency but they are not in phase...on the Y axis...but are in phase on the x axis

I'm sorry, but you're missing it completely. Maybe you should really listen to those who recommended some introductory lesson on signal processing, I don't know.

This statement is correct
....

Yes they are of different amplitude, which have nothing to do with phase, which in this case is ploted on x axis. 🙄
Take a step back, you've focused too much on something to the point to have lost point of references, the whole picture imho.
And no amplitude isn't a domain in itself. Time and freq in the case of analysis are but amplitude no.

I always thought they were in phase...I still do.... I was just entertaining mabats notion that he could determine amplitude using phase...but he recanted on that statement so we are back to what I've been saying the whole time....just until Geddes educated me, I used the wrong words technically
"Start up transient" how come Earl is only person I've heard use that term till this day...But you say I need to go back and read the textbook?
Tell me more....
I'm figuring this stuff out without even reading the book lol
It just makes sense to me...
Oh I get it now… The frequency domain is not even a thing because frequency is a product of time...So that only leaves the time domain and the amplitude domain....

I can explain it to you but I can't understand it for you. I pointed to characteristics of the waveform and Earl was able to give me the technically correct name on it pretty quickly
Frequency domain
From Wikipedia, the free encyclopedia
In physics, electronics, control systems engineering, and statistics, the frequency domain refers to the analysis of mathematical functions or signals with respect to frequency, rather than time.[1] Put simply, a time-domain graph shows how a signal changes over time, whereas a frequency-domain graph shows how much of the signal lies within each given frequency band over a range of frequencies. A frequency-domain representation can also include information on the phase shift that must be applied to each sinusoid in order to be able to recombine the frequency components to recover the original time signal.
Frequency domain - Wikipedia
I already agree that there are multiple domains... phase and frequency are two aspects of the time domain.... we just have a bunch of people here who have never entertain the idea of an amplitude domain

camplo, amplitude is in the frequency response. Look at any frequency response graph. Pick a frequency on the x-axis, for example 1000Hz, put a finger on the frequency response line at 1000Hz and then look for the amplitude on the y-axis.
