What is scalogram?

The scalogram is the absolute value of the continuous wavelet transform (CWT) of a signal, plotted as a function of time and frequency.

What is a Scalogram wavelet?

Wavelet scalograms visualize the time frequency localization property of the discrete wavelet transform. In a scalogram, each detail coefficient is plotted as a filled rectangle whose color corresponds to the magnitude of the coefficient.

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.

What is spectrogram and how it is computed?

The spectrogram is a three-dimensional plot of signal amplitude versus time and frequency. It is typically computed using the Short Time Fast Fourier Transform (STFT). — Click for http://en.wikipedia.org/wiki/Spectrogram.
