AMX Digital

A few days of getting to know the STM32Cube IDE... I'm totally overwhelmed with what I've been able to see in the IDE so far.
It is becoming clear to me that it will take me a lot more time to get used to this kind of change.
Fortunately, I started to find regularly very good "lessons" on YouTube.
I'm bothered by the "burden" of Arduino... habits and long-term work with it.
I think it would be easier for me to start from the beginning without any prior knowledge.
But now it's too late.
To say that I am delighted with IDE is an understatement.
But there is still so much to learn and practice.
Move on...

That graph clearly demonstrates the need for a multi-channel ADC.
Analog demod solution looks so better choice now.
Especially after the daunting demands of direct sampling.
Thanks to Your and Willy's goodwill; in a couple of posts I learned something that I have not been able to understand for years.


It will be an interesting "math" to take those samples later. An "block" algorithm for further processing should be drawn/written. But in "folk words". To make it easier to understand.

Hi Carl and Ivconic I'am perhaps a bit stupid but I don't understand why you need to have more than one ADC to analyse the RX signal ?
If one ADC transform all the analogic signal into a digital one why the processor couldn't take samples for RX25, RX5a, RX5b and RX5c on the same channel and separately analyze them with the DSP.
Could we imagine the same Digital signal connected to many pins of the processor to analyze independently all type of RX signal ?

With either analog demods or direct sampling, one ADC will do the job. For the analog demods, I would choose a multi-channel simultaneous sampling ADC like the ADS131E04. But you could also do it with a single channel ADC and a mux.
