I have a little problem with a program that I wrote and I am a little stuck. I have a vector that consists of 20,000 sample points. These sample points create a sine wave that only consists of the negative half of the wave. Sometimes there is a "glitch" or "spike" in this wave that I want to filter out of my measurements but am stuck. I take a frequency measurement and a Min and Max measurement. Also, this has to work for a general case, i.e. a larger wave/smaller wave or even a wave with a smaller amplitude or higher frequency. Below is the excel file that I used to graph the points, then my program reads in these values one by one that populates a vector. I have also added the spike to this file to get a visual of the graph. This graph repeats itself all the way to 20000, but the spike does NOT get repeated.
