Passive Filters, Data Transmission and Equalization Oh My!

[Shahriar] is back with a new “The Signal Path” video. It has been a few months but it is okay because his videos are always packed full of good information. Some new equipment has been added to his lab and as an added bonus a quick tour of the equipment is included at the start, which is great if you like drooling over sweet machines.
The real focus of the video is high speed data communications, getting up into the GHz per second range. [Shahriar] covers filtering techniques from simple RC low pass filters to pretty complex microwave filters. Explaining frequency and time domain measurements of a 1.5Gbps signal through a low bandwidth channel. He also shows how equalization can be used to overcome low bandwidth limitations.
It is an hour long video jam packed with information, so you might want to set aside some time and have a pencil on hand before going in. It is well worth it though, so join us after the break.

@ Kevin Dady,
I don’t wanna be a dousche but “GHz per second range” is incorrect… Hz is already “impulse/beat/wave/etc per second thus GHz per second here refer to half the derivate of what you’re talking about,somehow closer to the jerk (or acceleration of the frequency ) rather than the freq.
I state again: Not intended to blam you,just to inform, you can delete my comm once it’s corrected.
Thanks
