Introduction to MATLAB, A Complete MATLAB Beginner's Study Guide

MATLAB is a high-level language and communicating atmosphere for mathematical computation, visualization and programming. MATLAB stands for MATrix LABoratory and was invented by MathWorks. The vast availability of inbuilt functions allow you to find solutions faster, developing GUI easily as compared to spreadsheet or other programming languages. Here CircuitsGallery presents a MATLAB basics course with common MATLAB basics questions. Series of…

Phase Shift Keying (PSK) Modulation Code in MATLAB

Phase Shift Keying PSK matlab waveform

Binary Phase shift keying (BPSK) is one of the basic modulation schemes in which the phase of the carrier signal is varied or switched according to the input message pulses. When the modulation input is at logic 1, a finite number of cycles of a sinusoidal signal are transmitted and when the input is at…

Amplitude Shift Keying (ASK) Modulation Code in MATLAB

Amplitude shift keying (ASK) matlab waveform

Amplitude Shift Keying is one of the basic types of digital modulation techniques. In ASK, amplitude level of the carrier signal is switched according to the binary information, keeping the phase and frequency fixed.We had already discussed about ASK modulation circuit before. Here we will provide some matlab help for you on ASK simulation using…

MATLAB code for Frequency modulation (FM) with modulation index

FM waveform simulation in Matlab

How to generate frequency modulation (FM) in MATLAB? Before that we must know what is FM (frequency modulation). In FM, frequency of the carrier signal having high frequency is varied in accordance with the instantaneous amplitude of the modulating signal having low frequency. Frequency modulated signals are widely used in television and radio transmission systems.…

How to draw (plot) a circle using MATLAB?

plot circle in MATLAB

How to draw a circle in MATLAB? This is a commonly asked question from many MATLAB beginners. Here is the MATLAB code to plot a circle. The transfer characteristics between sine wave and cosine wave will give a circle. So here first we define a sine and a cosine wave, then plotting a circle in…

MATLAB code for Amplitude modulation (AM) with modulation index

AM Modulation waveform in matlab

How to generate Amplitude modulation (AM) using MATLAB? AM is a method of transmitting signals, such as sound or digital information, in which the amplitude of carrier wave is changed according to the message signal. AM is widely used in electronic communication field. The plotting of AM signal using MATLAB is very easy. Here we…
