Signal to background ratio assay

WebOct 21, 2024 · All analytical signals are comprised of two components. These are the signal, which equates to target information, and the noise, which is fluctuations in a certain signal. These fluctuations are often random and are expressed as the standard deviation (σ or s). A given signal can be thought of as the sum of all signals at one specific ...
