Want code to detect the peaks of absolute value curve
 

Re: Peak Detection

Do you have an analogous signal? Then absolute value and peak detector would require two or three OP. Peak detector could either have a return time constant or a reset switch.
 

Peak Detection

i want to get the magnitude of the peak values using matlab.. i want the code...
 

Re: Peak Detection

what is your signal?
is it a function of time?
at first please write your function.
 

Re: Peak Detection

Dear kalais_eee

if you want that somebody helps you you should be a little bit more polite!

Instead of "I want ... I want..." would be better if you had used "Please, I would ... Thank you".

Anyway, you could try a function which implements this pseudo code

if(current value > StoredPeak)
StoredPeak = CurrentValue
else
StoredPeak = StoredPeak * DecayConstant

where choice of the decay constant depends on the application.
