Signal-to-Noise Ratio Harvest Exchange Updated Sun, Jan 22, 2017, 7:53 PM ...

To be intelligible, any data that's transmitted by any means, electronic or otherwise, must rise above any accompanying noise. The measure of that intelligibility is called its signal-to-noise ratio.

Measured in decibels, signal-to-noise ratio (SNR, S/N) measures the clarity of the signal in a circuit or a wired or wireless transmission channel. See interference-to-noise ratio.

So by focusing on the short-term variability (or random noise) of your investment, there's a high likelihood that you'll completely miss the signal - i.e., the investment's long-term 90%+ winning ...

Miss the first segment? Here it is: Part I Sources of Timing Jitter, Amplitude Noise, and Signal Integrity Jitter and noise are deviations from an ideal signal. Jitter and noise can have many causes.

Combining images produces a superior signal-to-noise ratio. Compare the single 450-second image on the top to the one on the bottom, which resulted from combining (stacking) eight 450-second images.
