the convolution of a signal is to filter the components of the signal.
The convolution does not mean the masking.
Masking means it is going to remove all the masked components(both high and low frequency components).But convolution is going to remove any one (either low r high frequency) depending upon the filter response.
there is a big difference between circular and linear convolution , in linear convolution we convolved one signal with another signal where as in circular convolution the same convolution is done but in circular patteren ,depending upon the samples of the signal
for finding convolution of periodic signals we use circular convolution
Convolution is particularly useful in signal analysis. See related link.
circular convolution is used for periodic and finite signals while linear convolution is used for aperiodic and infinite signals. In linear convolution we convolved one signal with another signal where as in circular convolution the same convolution is done but in circular pattern ,depending upon the samples of the signal
pls tel me in details with example
The convolution of the input signal with the filter produced the desired output response.
There are a lot of convolution functions in matlab, mostly in the signal processing toolbox, so it depends on what you want to do. Matlab has extensive help files available online.
Convolution in science is a mathematical operation that combines two functions to produce a third function representing how one function modifies the other. In image processing and signal processing, convolution is used to process and analyze data by applying a filter or kernel to an input signal. It is a fundamental concept that allows for extracting features or enhancing signals in various scientific fields.

Convolution is a mathematical function derived from two given functions by integration that expresses how the shape of one is modified by the other. Convolution is used in GPS receivers to simultaneously identify the satellite transmitting a signal and measure the time delay from transmission by that satellite so that the distance between the satellite and the receiver can be determined. Modern GPS receivers have 12 independent convolution channels so that all 12 satellites above the horizon can be tracked.
A convolution is an integral that expresses the amount of overlap of one function as it is shifted over another function.You can use correlation to compare the similarity of two sets of data. Correlation computes a measure of similarity of two input signals as they are shifted by one another. The correlation result reaches a maximum at the time when the two signals match bestThe difference between convolution and correlation is that convolution is a filtering operation and correlation is a measure of relatedness of two signalsYou can use convolution to compute the response of a linear system to an input signal. Convolution is also the time-domain equivalent of filtering in the frequency domain.
yes we can perform linear convolution from circular convolution, but the thing is zero pading must be done upto N1+N2-1 inputs.
