What are the units of amplitude and sample value in a sine wave loop?

[btb4198]

for (int n = 0; n < 52920; n++){
F = Amplitude * sin(2 *pi*n* Frequency/44100) ;
}
what are the units of Amplitude ?
I know Frequency is in Hz
also what are the unit of F?

 

[anorlunda]

It appears to be an expression for the instantaneous values of something which varies sinusoisally. But without know what that thing is, we can't tell the units.

It could be a swing. It could be electrical current, or voltage or power. It could be the height of a liquid. It could be almost anything.

The sine doesn't have units, so F and Amplitude have the same units. But what those units are, depends on what physical quantity you're describing, as anorlunda said.

what if it is a sound wave?

what if it is a sound wave?

That's still not enough. You're not going to get anywhere asking people to guess.

Does the signal come from a microphone or a pressure sensor? Information like that will provide your answer.

so that signal I posted, is just a sinewave I make up. I did not get it from anywhere...

So there is no answer to your question.

Then you can make up the units as well.
