Convolution - Derivation, types and properties

Convolution – Derivation, types and properties

December 4, 2019

Convolution, at the risk of oversimplification, is nothing but a mathematical way of combining two signals to get a third signal. There’s a bit more finesse to it than just that. In this post, we will get to the bottom of what convolution truly is. We will derive the equation for the convolution of two […]

Discrete Time Fourier Transform (DTFT) vs Discrete Fourier Transform (DFT)

Discrete Time Fourier Transform (DTFT) vs Discrete Fourier Transform (DFT)

In this post, we will encapsulate the differences between Discrete Fourier Transform (DFT) and Discrete-Time Fourier Transform (DTFT). What is DTFT? DTFT stands for Discrete-Time Fourier Transform. We can represent it using the following equation. Read the equation carefully. Here, the signal has a period of 2π. What is DFT? DFT stands for discrete Fourier […]
