wave mixing correlation

Understanding Audio Phase

In fact, if we were using a pure sine wave, combining both signals out of phase would result in silence, since the sounds would literally cancel each other out. Example 2: Left and right channels out of phase. Many stereos and most mixing consoles allow you to do this, but even in stereo, there are some telltale signs of phase problems. Get price

Diagnosis of mixing between middle latitudes and the polar

1. Introduction [2] Tracer‐tracer correlations are often invoked to assess transport and mixing in the stratosphere. Pairs of long‐lived tracers generally form compact correlations (e.g., Goldan et al., as referenced by Plumb, Kelly et al., and Fahey et al.).Different regions of the atmosphere are characterized by different such tracer relationships, e.g., the tropics and the midlatitiudes Get price
