What are the types of spectrogram?

There are two main types of spectrograms – the discontinuous type, and the continuous type. These two types refer to how the data is acquired, processed and displayed in the spectrogram.

Is spectrogram a Stft?

Description. s = spectrogram( x ) returns the Short-Time Fourier Transform (STFT) of the input signal x . Each column of s contains an estimate of the short-term, time-localized frequency content of x . The magnitude squared of s is known as the spectrogram time-frequency representation of x [1].

What is spectrum and spectrogram?

A spectrogram gives a running display of a sound signal as it occurs in real time; a spectrum, on the other hand, gives us a snapshot of the sound at a specific point in time. A spectrum can enable you to see, for example, the energy distribution over the different frequencies of a single vowel, like [i].

What are the three dimensions of a spectrogram?

A common format is a graph with two geometric dimensions: one axis represents time, and the other axis represents frequency; a third dimension indicating the amplitude of a particular frequency at a particular time is represented by the intensity or color of each point in the image.
