I'm using a myDAQ to measure a perioidic voltage signal, and I want to find the maximum and minimum of this signal. When acquiring the signal though, there seems to be a large impulse in the start of the acquisition data shown in one of the attachements. The capture is from a probe from before any filtering is applied to the signal. I'm not sure if this is an effect of the signal acquisition or something I am doing with the signal filtering, and I am new to signal processing in Labview in general.
In the picture, I acquire 2 signals at 1, split the signal at 2 (top signal is of interest), filter at 3, scale at 4, and display at 5.
Can anyone point me in the right direction of what could be going on in my code?
