A practical example of how pulses are transmitted and received. A bit about modulation, demodulation and avoiding everything that is mildly complicated

Some Stuff About RADARs, pt. 1 – Range, Power And Doppler
Just the tip of the iceberg on how RADARs work
Ports – From 3D to 0D
Disclaimer: This issue is boring. Not only because it has nothing to do with Cyber, AI, machine learning, etc. (nor do most of the things I do and write about). It’s boring because it has to do with only one…
QUCS-S: Return Of The OpenSouce!
Another Linux user open wound: For ages I have been stuck without proper circuit simulation in Linux. I don’t define myself a power-user (only as a super user, but only when I run sudo) as I run Ubuntu, but that…
Obsessive, Compulsive, Yet Hardly a Disorder
So this has happened to me more times than I can remember. Somebody tosses a piece of junk or another out on the street. I pick it up, hoping that this time it will work “out of the box”. Sometimes…
The Perils of Port Extensions
This post concerns a much more simplified version of the previous one. Last time we dealt with an arbitrary length line, with an unknown characteristic impedance. For that matter, a double length line de-embedding structure was suggested. In this post,…
De-Embedding 2 Whole Degrees of Freedom
In the last post we discussed de-embedding a simple transmission line, namely a phase shifter and attenuator. Surprisingly, most structure that we might need to de-embed will be far from that, to say the least. To maintain a methodical approach,…
Basic De-Embedding, 1st Order Model
It occurred to me recently that although I named this site RF with care (for reasons I definitely cannot recall any more), I have not really written here anything RF or EM related in any way. So to start it…
