It is the number of full cycles that the waveform achieves in 1 second. The unit for frequency is Hertz, Hz, or cycles per second. When we say “cycle” we simply mean the passing of one peak and one trough of …

In probability theory and statistics, the Jensen – Shannon divergence is a method of measuring the similarity between two probability distributions. It is also known as information radius ( IRad) [1] [2] or total divergence to the average.
