A slow download is usually blamed on routers, software, or the service provider. Those layers matter, but underneath every link sits a limit set by physics: how much information a …
A pattern I keep seeing on the bench goes like this. A prototype modem shows a clean spectrum, the signal sits well above the thermal noise floor, and the link budget says there is …
Digital engineers are trained to treat “more” as a default win: higher clock rates, wider bandwidths, deeper bit depths. Applied to analog-to-digital conversion, the …
Every communication system starts with the same goal: move a signal from one place to another and recover its meaning at the far end. In practice the signal passes through copper, …
