What can a spectrogram show?

A spectrogram is a visual way of representing the signal strength, or “loudness”, of a signal over time at various frequencies present in a particular waveform. Not only can one see whether there is more or less energy at, for example, 2 Hz vs 10 Hz, but one can also see how energy levels vary over time.

How are spectrograms useful?

As a collection of time-frequency analyses, the spectrogram can be used to identify characteristics of nonstationary or nonlinear signals. For this reason, a spectrogram is a helpful tool for analyzing real-world data where there are various frequency components and/or mechanical and electrical noise.

How many types of spectrograms are there?

There are two main types of spectrograms – the discontinuous type, and the continuous type.

What is the frequency range of a spectrogram?

What is a Spectrogram? A spectrogram is a means for viewing the frequency content of a seismogram as it changes with time. Once each minute, we calculate the frequency spectrum of the seismogram between 0 and 10 Hz.
