Baluncore replied to the thread differential line insertion loss behaves very problematic in the oven.The thing that will change most with temperature is the thickness of the PCB. What material is the PCB? My guess is that your input... -
Baluncore replied to the thread Stargazing Falcon 9 predicted lunar impact.Yes it did, but it was very hard to see. We must wait a few days for the radar image of the crater it produced. -
Baluncore replied to the thread Implementing Kramers–Kronig causality check on real VNA s-params.You tell me you want to visit the region of Kramers-Kronig, that is a long journey. Reading about a process, is not a substitute for... -
Baluncore replied to the thread Implementing Kramers–Kronig causality check on real VNA s-params.The way a process is defined mathematically, is not necessarily the way it is computed numerically. "Multiplication by the sign function... -
Baluncore replied to the thread Implementing Kramers–Kronig causality check on real VNA s-params.There is nothing simple about the Kramers-Kronig method. Do not start with real data, you will need to follow a step-wise process of... -
Baluncore replied to the thread Undergrad Soccer Ball Resistor Puzzle.Nerds are people too, but they are non-linear. In normal times, when a nerd stands near a group of n people, that makes n+1 people. In... -

Baluncore replied to the thread Undergrad Soccer Ball Resistor Puzzle.I have noticed that many of these problems reduce to a branching ladder network, a continued fraction. -
Baluncore replied to the thread Graduate An electrolytic capacitor keeps charging by itself.Fifty years ago I remember reading about a device from fifty years before that. There can be rectifier action in every asymmetrically... -
