Intro to Electrical Filters
So Many Electrical Filters, So little Time…
Do an online search for the word filter and you’ll get a ton of results ranging from car parts to coffee. This post, however, will focus on electrical filters.
Even if we narrow our search down to the term electrical filter, we’re still going to get a ton of results. After all, entire books have been written on electrical filters (I should know, I own one).
That’s because even in the realm of just electrical filters there are many different types.
We have passive and active filters. Digital and analog filters. Filters bearing the name of their creator like the Butterworth filter, Bessel filter, and Chebyshev filter (don’t ask me how to pronounce that). And there’s more.
