WebA spectrogram is like a photograph or image of a signal. A spectrogram plots time in Y-axis and frequencies in X-axis. A spectrogram also conveys the signal strength using the colors – brighter the color the higher the energy of the signal. A spectrogram explains how the signal strength is distributed in every frequency found in the signal.
