Comodulograms showing the Osipova coherence metric by varying the sliding Fourier transform window size. All panels use the same 40 Hz high-frequency signal amplitude modulated by a 15 Hz signal. The x-axis shows the modulation frequency fm, and the y axis depicts the carrier frequency fc. CFC is barely detectable at a window size of 15 cycles and is not visible at a window size of 30 cycles.
