WebJul 3, 2013 · According to high-school physics, light frequency and wavelength are inversely proportional, and their product is the speed of light. But when discussing spectral power, … WebJul 9, 2014 · It uses a sliding window and counts how many times a local peak appears as a maximum as window shifts along the x-axis. As @DrV suggested, no universal definition of "local maximum" exists, meaning that some tuning parameters are unavoidable. This function uses "window size" and "frequency" to fine tune the outcome.
