Function

This plugin estimates the phase of inputs an input signal within a specified passband in real time. Its primary purpose is to enable closed-loop stimulation, typically in combination with the Crossing Detector and either the Pulse Pal or an external stimulation system that receives ZeroMQ events (for example, the LabVIEW implementation here). It can also output the magnitude or imaginary component of the band-limited analytic signal instead of the phase. (The "PH+MAG" mode outputs both phase and magnitude, in separate channels.) Finally, the visualization tab or window can receive TTL events and display the delayed but precise phase of a specified input at the event onset samples in a rose plot. This allows real-time monitoring of stimulation accuracy.
