First, I have reviewed close-match questions, but can't find something that seems to match what I'm looking for. Also, it's been 30 years since college, so forgive me for forgetting stuff.. :)
I am analyzing IP Packet data. I am creating bins (of varying window sizes.. The window seems not to be sufficient to remove/smooth the harmonics) to count the frequency of certain attributes/behaviors within the data. From this, I am trying to determine fundamental frequencies that activities are occurring. I believe that the artifacts that I am seeing are harmonics since the data tends to be pulse/bursty, resulting in what amounts to a square wave. (see below) . In this sample data, as you can see, there is a strong signal occurring every hour, over the course of 47 hours, yet it is almost impossible to "see" because of the harmonics. (at least, that's my guess/intuition)
Is there something that I can do to smooth things out so that the harmonics are suppressed (or largely suppressed) and I only see the fundamental frequencies? I feel as though I've forgotten something basic.
