Communications System, End to End

 
 
The unified communications field, as it's now being called, is getting very advanced. Every year, new innovations are coming out that make the field of communications progress faster and faster. From cellular technology and the 4G mobile networks, to advanced business systems, that allow for real time visual conferences to take place and business directors around the world to communicate. Below are pictures on various ways that Communication happens from signal noise and satellites, to receiver systems, to your ears.

Bandwidth - SNR
  Signal to Noise Ratio & Dynamic Range
For a given signal bandwidth, ideally, the receiver bandwidth should be the same. However, if the receiver is, say, twice the necessary bandwidth, the Signal-to-Noise Ratio is diminished, i.e., the noise has doubled.
