Adaptive signal processing

I have simulated ECG waveform,I need to delay this by 16 samples and give it to the "AFT filter signal and update coefficients.vi" as d(n) and original ECG as x(n).But it says length of these signals are different and throws an error.For the delaying part, I have tried Z transform delay and also by adding delay to the t0 of the waveform.But none of them worked.I am still a beginner in Labview.Please do help me.

How did you implement the delay? You can easily check the lengths by using Get Waveform Componenets and checking the Size of the Y arrays.

 

Please post your VI so that we can help.

Please go through the following discussion thread to understand the insertion of phase delay between two waveforms using FFT function.
