thank you sir ,
i used this same code which is given but i changed filter high pass as low pass (5 order, 5 freque ncy)and low pass filter as high pass(2 order, 0.8 frequency)
i got the same base line as well as peak amplitude of the waveform ...
but i have to find the peak amplitude value (from base to peak) , it shows oly peak value (from zero to peak)..what i have to do? or otherwise how can i shift this negative lower value in the waveform to zero line? if it is possible means the same peak detector much usfull for detecting peak amplitude in waveform...
here i attached the vi and data...
