When you search online for ENBW you’ll likely find a list of sites related to EnBW AG, a German energy giant (which, on a totally unrelated note, we were a customer of until recently). While energy is quite relevant in the context of this post, EnBW has nothing to do with it. This post is …
Sometimes signals can be stubbornly non-periodic. This can make digital signal processing so much more annoying. The supposedly simple act of plotting the spectrum ends up being a game of trial-and-error, or requires making a decision that involves prior knowledge of what one would actually like to know in the first place. We’ll have a …
As a (late) Christmas present I thought I’d share my method of determining the required OSNR (ROSNR) value for a transmission system in simulations by means of the Monte Carlo method. Recently, I do prefer the error vector magnitude (EVM) as a figure of merit, but not a lot of people share this view. Many …
Since I have so much to do with the discrete Fourier transform (DFT) – both recently and not so recently – I always wanted to make a sort of “cheat sheet” about it with the most important relations of the various time and frequency dimensions and some of the more important transform pairs all on …
