Maximum frequency

[Jarfaut]

Good afternoon comrades!

Maximum frequency of generation and analysis by the built-in modules of the Flowstone system.

What is the maximum frequency?
Can frequencies greater than 100 or 500 kHz be generated and displayed graphically?

Good time, everyone!

Hello and welcome to the forum!

FlowStone is limited by the sample rate set on the audio interface, so at 44100 Hz that would be the theoretical maximum that can be evaluated or used. For audio the limit would typically be half that frequency (Nyquist).

BTW I saw your other posts about your post not being posted, but new users automatically get sent for moderation for their first few posts. That's me that is!
It means you might have to wait up to a day for me to approve, depending on when you make a post.

Thank you, Spogg, for the answer!
Why am I interested in the question about the frequency inside the module...(?) The point is that I want to simulate the operation of a simple AM-radio tract. Of course, it can be partially simulated at ~20 kHz, but it won't be quite the right thing.
Harmonic leakage is not so bad in inaccessible range, starting at least from 100 kHz. Even better from 500 kHz.

Interesting.
Is this to make an audio effect that sounds like am radio?

Spogg, of course such a model can also be used as an effect, if necessary. Since, in the end, any radio serves a band of the audible range. Looking only at the oscilloscope is not the ultimate goal of receivers.
