The Analyze CHOP looks at the values of all the values of a channel, and outputs a single-number result into the output. The output is one sample long. It can analyze for maximum, average, peaks and other aspects of a channel.
Parameters - Analyze Page
Function - This menu determines the function applied to the channel.
- Average - the average of the channel.
- Maximum - the maximum value of the channel.
- Minimum - the minimum value of the channel.
- Sum - the sum of all the samples in the channel.
- RMS Power - the RMS (root-mean-square) of the channel.
- First Peak Value - the value of the first peak in the channel.
- First Peak Index - the index of the first peak in the channel. The index of the first sample is 0.
- Highest Peak Value - the value of the highest peak in the channel.
- Highest Peak Index - the index of the highest peak in the channel.
- Lowest Peak Value - the value of the lowest peak in the channel.
- Lowest Peak Index - the index of the lowest peak in the channel.
- Total Peaks - the total number of peaks in the channel.
Allow Start Peaks - If the values of the first 2 samples are v0 and v1, if v0 > v1, count it as a peak. The default is to never count the first sample as a peak.
Allow End Peaks - If the values of the last 2 samples are vn and vm, if vm > vn, count it as a peak. The default is to never count the last sample as a peak.
No Peak Value - When no peaks are found, make this number (default is
-1) the result that is output. When the Function is set to Peak Index or Peak Value, it is a way to detect that no peaks were found.

"This is where RMS comes in to play. Skipping the potentially brain damaging
math, it turns out that the RMS or effective value of a sine wave is 0.707 times the peak value. (1/0.707 is the square root of two; that is, 1/0.707 times 1/0.707 equals 2.) "
Which is exactly what sending a default Wave CHOP into the Analyze CHOP gives when you select "RMS Power". Yahoo!
