Putting the Decibel to Work

2023-05-01T17:15:20-04:00April 26th, 2023|

Welcome back, tech enthusiasts! I'm your host Brady Volpe, founder of Nimble This and the Volpe Firm, and I'm thrilled to be here with another exciting episode of "Get Your Tech On." Today, we have a very special guest with us, Ron Hranac, who will be the main presenter on our topic, "Putting the Decibel to Work (see video on Youtube)" As many of you know, the decibel is a fundamental unit of measurement in the world of telecommunications and is used to express everything from gain and

Why is QAM Getting Me Down?

64-QAM lower than Analog video on the downstream?  64-QAM lower than 16-QAM on the upstream?  Why is a 6.4 MHz channel lower than a 3.2 MHz DOCSIS channel?  Someone said there is math for all of this, but man QAM is getting me down! These questions come up in every lecture I give on DOCSIS.  Why do QAM measurements show up at different levels on a spectrum analyzer than analog measurements.  What's more, why do QAM signals of different bandwidth have different levels?  Some of the questions have
