Window detector

[tinamoli]

Hello All,

in the vi below I have used peak detector ,to find the  peak which is higher than threshold value,,

BUT,

can I have a range for threshold value,that peak  detector function act as window detector ,and giving a window of peak detected?

for example:

if I wire a range of (0 to 0.2) as  threshold ,and the peak detector detects all peaks within this range?

Hi tinamoli,

you can first detect all values greather than the low value of your range. Detect then all values smaller then the high value from the before created portion.

Hope it helps.

let me explain what i want to do in here ,

in the ecg1.png  below if i should calculate all these parameters PR interval ,P duration,PR Interval,QRS interval QT interval,HR.

also;

P amplitude ,Q amplitude, R amplitude,S amplitude,T amplitude.

for the moment:

in the HR.vi  below  how i know the location for  P amplitude,in reality P amplitude is (0.1_0.15)mv,if i adjust the threshold to 0.1 ,it dosent work.

Also,

i would be very happy if you could calculate any parameter i mentioned above,except the HR ,as i shown below in HR.vi
