According to the convolution theorem for Fourier transform, the convolution of two signals in the time domain is equivalent to the multiplication in the frequency domain. Therefore, if two signals are convolved in the time domain, they result the same if their Fourier transforms are multiplied in the frequency domain. For example, if x(t) and h(t) are two signals in the time domain and their Fourier transforms are X(ω) and H(ω) respectively. Then, their convolution in the time domain is given by, f(t) = x(t) * h(t) Here, the symbol ‘*’ represent the convolution of two signals. And the ... Read More

In digital signal processing and image processing, the convolution is a crucial mathematical operation. The primary function of the convolution is to combine two signals to produce a resulting signal. The resulting signal specifies the interaction between the two signals that we combined. In MATLAB, we can perform the convolution of two signals by using a built−in function ‘conv()’. This MATLAB function performs the convolution by using a discrete approximation of the integration. For this, it uses discrete samples of the input signals. Syntax The following is the general syntax for the ‘conv()’ function, a = conv(x, y, shape); ... Read More
