Everything Students Should Know About Convolution of Discrete Signals
Convolution is a way to combine two signals to form a third signal. So, convolution of discrete signals simply means combining two discrete signals to form a third signal. In this post, we’ll give you a step-by-step guide on how to perform convolution by graphical method. We’ll also share some real-life examples of discrete signal…

Introduction to Signals & Systems
We studied about the basics of signals and systems in this previous post: Signals and Systems Basics In this post, we’ll dive deeper into the definition of a signal and the definition of a system – along with each one’s types. What are signals and its types? Signals are functions of one or more independent…

Signals and Systems Lab Report3D Brain Signal Simulation on MATLAB
Below you will find MATLAB code for 3D Visualization of a simulated brain signal. MATLAB Code t = linspace(0, 2*pi, 1000); frequency = 1; amplitude_cos = 1; amplitude_sawtooth = 0.5; brain_signal = amplitude_cos * cos(2*pi*frequency*t) + amplitude_sawtooth * sawtooth(2*pi*frequency*t); figure; plot(t, brain_signal, ‘LineWidth’, 2); title(‘Simulated Brain Signal’); xlabel(‘Time (s)’); ylabel(‘Amplitude’); grid on; figure; subplot(2, 1,…
