Amalga promised to bring the data together in one place and find the signal in the noise.
FORBES: How Microsoft Moved Out Of One Health Business To Protect Another
Unless these systems are designed carefully, the transmitted signal can cause noise in the receiver, making it not nearly as sensitive.
Again, you have to deal with signal issues in high-RF noise environments, deal with materials issues acting as RF shields (like in many computer rooms or anything with lots of metal in it), and you have to balance the convenience with the somewhat-increased security risk.
Bigger pixels also emit more current, allowing their signal to swamp the electrical noise in the system.
Over time, however, we learn how to install the right filters that increase the signal-to-noise ratio in the information we receive.
The miniaturization of pixel size impacts performance of light sensitivity and signal to noise ratio (SNR) in today's 1.12 micrometer pixel image sensors.

It is for this reason that The Signal and the Noise is essential reading in the era of Big Data that touches every business, every sports event, and every policymaker.

Then they found a better way to mount it in the driver's helmet and added signal processing to cancel out extraneous noise.
Moreover, with digital you can also move that information around without losing it in the surrounding noise, as this often happens with an analog signal.
If local wireless networks proliferate as expected, the traffic will generate so much noise that nobody will be able to get a clear signal, especially in cities that already have thousands of transmitters in offices and homes.
The Signal And The Noise is aptly titled as we humans still make many of the same mistakes our animal brethren elsewhere in the world make, prone to look for patterns or meaning in the noisiest of data sets.
