Peak detection at same time

[hussey]

Hello

I have two wave A and B with 10000 sample point.

Now I want to find Max and Min peak value from wave form A and correspond to it I want to know respective value of wave B.

So at thw end finally I will get Max value of A and it's respective value of B.

So for that I want to know basic idea.

Thanks

-I guess similar type of questions have been asked and answered many times.
-Check these for getting max and min peak values

-Then use time value where peak happens in wave A to wave B and get the values.

After the waves have sampled. Just use "Array Max & Min" on the A array, or peak detection

Then connect the indexes of the max and min to "Index Array" of the B array.

Hello

I think there is one misunderstanding by you,

I want value of Wave B(whatever not necessary that both wave will give me Max and min point at same sample point) when I got Max value of wave A.

Thanks

That's exactly what got explained, or showed by me and uday.

-First get the max value where it happens in wave A.
-Use that time value in wave to get value in wave B using simple index array.
still not clear?
