Computation of Convolution (Continuous Time (CT) case) The convolution of two signals x(t) and h(t) in continuous-time LTI system will be represented symbolically as y(t)= x(t)*h(t) Mathematically it is given by +∞ y(t)=∫ x(τ)h(t- τ)dτ -∞ this is also referred as ...

Convolution is important because filtering of discrete-time signals using finite impulse response (FIR) digital filters is basically a linear convolution of the signal sequence with the impulse response sequence of the filter. It is also a very fundamental operation in DSP and therefore deserves more...

To do this however, we are going to switch to a different physical analogy (don't worry, we will come back and solve the wave problem in a bit!). The reason for our switch-up is just to simplify the problem at hand: with waves we have to worry about thetime dependenceof our respo...
Let f¯(t) be a continuous time signal defined over [0, 1]. Let f[n] be the discrete signal obtained by a low-pass filtering of f¯ and uniform sampling at intervals N−1. Its discrete wavelet transform can only be calculated at scales N−1 < s < 1, as shown in Figure ...
In continuous-time LTI systems, it becomes: The asterisk (*) denotes the convolution operator. Now, let’s explore the various methods of computing linear convolution. 3. Linear Convolution: Methods of Computation Using linear convolution, we compute the convolution of two sequences to determine ...
In electrical engineering, the convolution of one function (the input signal) with a second function (the impulse response) gives the output of a linear time-invariant system (LTI). At any given moment, the output is an accumulated effect of all the prior values of the input function, with...
