Amplitude Modulation Simulation Lab Manual Using Multisim - Experiment 2: Amplitude Modulation and Demodulation Objective Amplitude modulation (AM) is one of the simplest methods for modulating a sinusoidal carrier Consult your lab instructor for manual setup instructions. Preset: Requiredsettings are stored in memory location[1] of the function generator. To access. ECE 416 Fall 2003 Experiment # 3 Amplitude Modulation and Demodulation −→ −→ 1 Purpose Amplitude modulation (AM), still widely used in commercial radio today, is one of the simplest ways that a message signal can modulate a sinusoidal carrier wave. The purpose of this lab is for you to gain familiarity with the concepts of amplitude. ANALOG COMMUNICATIONS LAB (SIMULATION) MANUAL INTRODUCTION TO MATLAB.
The simulation of modulation schemes such as amplitude modulation and frequency modulation are designed using VI models are used as reference. ECE 2C Laboratory Manual 4 Infrared PWM Transmitter Overview Simulate the PWM circuit using MultiSim or Circuit Maker™ (circuit files available on the course web site). conceptually simple methods—Amplitude Modulation (AM) and Frequency Modulation (FM)—are illustrated in. There are different types of amplitude modulation like DSB-FC,SSB, SSB-SC,DSB-SC,VSB. Here we have done simulation using DSB-SC .We have suppressed carrier because carrier doesn't carry any information instead consume power.SSB-SC and VSB are the improvement in DSB-SC as they don't carry carrier with them hence requires less power..
The message signal used here is a pure sine wave generated using Wien Bridge Oscillator (WBO) and an FET based modulator circuit is used for the PAM modulation. The demodulation of the PAM signals can be done easily using a Low-pass filter. Fig. 1: Block Diagram Of Pulse Amplitude Modulation (PAM) { 1) Variable frequency sine wave generator. Amplitude Modulation - A continuous-wave goes on continuously without any intervals and it is the baseband message signal, which contains the information. We can use this formula for calculating modulation index value, when the maximum and minimum amplitudes of the modulated wave are known.. Circuit Design: Pulse Amplitude Modulation. September 30, 2013 By Ashutosh Bhatt . There are different kinds of modulation technique based on varying the properties of a pulse train. The Pulse Width Modulation (PWM) varies the width of individual pulses according to the amplitude of the modulating signal..
Nov 22, 2013 · The amplitude of each pulse corresponds to the value of the message signal x (t) at the leading edge of the pulse. The pulse amplitude modulation is the process in which the amplitudes of regularity spaced rectangular pulses vary with the instantaneous sample values of a continuous message signal in a one-one fashion.. Pulse amplitude modulation is a technique in which the amplitude of each pulse is controlled by the instantaneous amplitude of the modulation signal. It is a modulation system in which the signal is sampled at regular intervals and each sample is made proportional to the amplitude of the signal at the instant of sampling.. FM Modulation Using 555 IC January 09, 2018 modulation technique in which the frequency of carrier wave is varied in accordance with the instantaneous value amplitude of the modulating signal. its lab experiment .not simulation design.

In the pulse amplitude modulation, the message signal is sampled at regular periodic or time intervals and this each sample is made proportional to the magnitude of the message signal. These sample pulses can be transmitted directly using wired media or we can use a carrier signal for transmitting through wireless.. The code for amplitude modulation (AM) with control of modulation index (ma) has been developed using MATLAB according to conventional theory. In this code, it is considered the default value of ma equal to 1 for hundred percent modulation..
