Coherence control systems
WebAug 12, 2016 · By coupling to the target system, these mediator systems can function as state preparation, control, and measurement devices. To interact meaningfully with the … In signal processing, the coherence is a statistic that can be used to examine the relation between two signals or data sets. It is commonly used to estimate the power transfer between input and output of a linear system. If the signals are ergodic, and the system function is linear, it can be used to estimate the causality between the input and output.
