Convolution. Convolution is the most important and fundamental concept in signal processing and analysis. By using convolution, we can construct the output of system for any arbitrary input signal, if we know the impulse response of system.
The practical significance of Fourier deconvolution in signal processing is that it can be used as a computational way to reverse the result of a convolution occurring in the physical domain, for example, to reverse the signal distortion effect of an electrical filter or of the finite resolution of a spectrometer. In some cases the physical convolution can be measured experimentally by
circular convolution and its relation to linear convolution. An interpretation of circular convolution as linear convolution followed by aliasing is developed. As we will see in a later lecture, there is a highly efficient algorithm for the computation of the DFT and consequently it is often useful in practice to implement a convolution (for implementing a filter, for example) by computing the

A key difference between analog and digital image processing is that digital signals are quantized in both length and level, that is, the different values a digital signal can take are a finite, as is the length of the signal.
Circular convolution is the same thing but considering that the support of the signal is periodic (as in a circle, hance the name). Most often it is considered because it is a mathematical consequence of the discrete Fourier transform (or discrete Fourier series to be precise):

The digital signal is extracted as a continuous analog signal, i.e., the original audio signal, from the output terminal 20, after removing the high-frequency noise component by low-pass filter 19, and after step-wise conversion to an analog signal by D/A (digital to analog) converter 18.
If we wish to compute the pdf of their sum (i.e., if we need the pdf of X + Y ), we can use the convolution of f and g. Continuing with this logic, we can compute the pdfs of the summation of any number of independent variables.
