WebAddition of two incoherent signals of equal amplitude, such as the two tracks of a trumpet and a trombone: Vector diagram: 1 The total amplitude of 1.414 is a diagonal. 1.414 The vectors for incoherent uncorrelated signals . stand at right angles to each other . Calculation of the diagonal = √(12 + 12) (Pythagoras) 1 . 3. 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.
