Passive Analog Filtering
The passive analog filter is the simplest and compact way to filter analog signals. They are very reliable and require no additional power supply. All of these can be designed with a simple configuration of resistors and capacitors. The basic filter types are: Low pass High pass Band pass Band reject / Notch Critical Equations […]
Eagle Tip: Tame those Unrouted Airwires!
If you’re like me, you practically live in Eagle. A recurring issue (especially on more complex designs) is that you’re sure that you’ve routed everything, but Ratsnest is telling you that you have 6 unrouted airwares! Here I’ll show you how I semi-automated this process without the use of the autorouter or hiding layers.
