good when she's not a filter?
Always, that's why it's not a filter.

So you can reduce everything to the fact that everything is a function, then that everything is 0 and 1. What's the point?
a signal is a useful property that you want to emphasise (it is not some mythical forecast or sinusoid or whatever you have imagined).
noise is what prevents you from getting a perfect signal (it's also any blue thing that gets in the way).
filtering/compression is the process of separating the useful from the not useful, separating the signal from the noise.
There can be no signal on a quote chart, which would mean that there is information about the future that it contains. But since the chart is just a reflection of the actual exchange rate at the moment and for the past periods, it does not contain any information about the future.
So how do you live if for you history does not carry information about the future? Of course, it is not there in a ready-made form, but our deeds yesterday and today make up our state of affairs tomorrow. Not out of thin air, not by chance (at least not completely by chance), but from specific past events and states.
Started playing a game of whack-a-mole, got involved with bad company and went downhill -> went to jail or got a feather in your side. That's the future, from high probability history. Studied well, worked efficiently -> became a respected professional. Here's another future from another story, also with high probability. This is an example of a trend.
You take out loans on euphoria - there will be a long personal crisis and economy until you pay it off. Pay off - free funds appeared, growth started. Overstretched in work or sports - a long rest for recovery, without which it is impossible to continue at the same pace, during this time the results will decrease. Rested, returned to business and pumped better than before. This is an example of the cycle.
Drive property prices into the crapper by depleting consumer demand and burdening them with credit beyond their real capacity - be a fall in prices and a rise in defaults.
All of these things, are they not related or not obviously related to each other? No, they aren't. Can they be visualised as a graph? Sure. Can such graphs be used to judge fairly confidently the nearest direction from the top or bottom, and the overall trajectory? Well, in general, yes.
And what are the fundamental differences between these simple examples and larger ones, for example, the euro exchange rate, which, being high, makes local producers suffer, and being low - importers? The nature of the phenomenon is the same.
That's economics, son. Blue diploma 🤣
Economics is aware of cycles and takes them into account:

No, signal is not a useful property. Again with the definition game.
Then what is it?
Everything I've said, I've said from that position.
You should have first defined the meanings of the terms.

Well, from that perspective, of course it's dumb.
