Over the last few videos I have highlighted helpful circuits. In this video, I highlight an active filter setup utilizing an operational amplifier. Filters are very helpful when working with analog signals.  Often the range of frequencies needed are not across the entire band, therefore you need to filter out those that inhibit a clean sampling of data. These two filters, a low-pass and high-pass, can be used to clean up your signals.

Also in this video, I address some questions about the tools I use and offer a few comments on various tools that I use most often.
