Most modern routers offer two signal options (also known as “frequency bands ... tasks that require more bandwidth, like streaming in 4K and uploading large video files.

So the raw video signal and audio signals coming out of the sensors are plain analog signals except for frequency the bandwidth difference. Digital audio and video is again much similar except the ...

Especially in the frequency bands below 1 GHz ... between frequencies are smoothed to help reduce the effective bandwidth of the signal. Bluetooth Low Energy uses GFSK modulation.

Bandwidth and latency aren't the same thing, but they both greatly impact the quality of your home internet experience.

But as [Alan] explains, the action of keying the transmitter imposes a low-frequency square wave on the carrier, so the occupied bandwidth of the signal depends on how fast the operator is sending ...
