Lab manual for amplitude modulation

In amplitude modulation (AM), the message signal is impressed on the amplitude of the carrier signal. This results in a signal whose amplitude is a function of the message signal. Forms of AM: AM signals may be of various types such as. 1. Conventional double sideband AM (DSB-AM) 2. Double sideband suppressed carrier AM (DSBSC-AM) www.doorway.rug: lab manual. ylabel('Amplitude'); title('h = ().^t'); u = sin(2*pi*t); subplot(2,2,2); stem(t,u,'filled'); xlabel('Samples'); ylabel('Amplitude'); title('Sine'); s = conv(u,h); subplot(2,2,[3,4]); stem([],s()); xlabel('Samples'); ylabel('Amplitude'); title('Response for a sine'); Fig Sinusoidal Response. Using NI USRP Lab Manual 49 Printed on: 12/4/ © , Anees Abrol and Eric Hamke 5 Amplitude Modulation Summary This laboratory exercise has two objectives. The first is to gain experience in actually programming the USRP to act as a transmitter or a receiver. The second is to investigate classical analog amplitude.

3-LAB Manual Amplitude-shift keying (ASK) Experiment 6 Objectives: By the end of this experiment, the student should be able to: 1. Generate and demodulate an amplitude shift keyed (ASK) signal Introduction Amplitude-shift keying (ASK) is a form of amplitude modulation that represents digital data as. This laboratory manual has been prepared as a guideline to help students of undergraduate courses to carry out basic experiments in analog communication • Amplitude Modulation (AM) - the process of combining the message signal with the carrier signal and the two sidebands: the lower sideband. PCS Lab Manual Page 5 THEORY: Amplitude modulation is one of the earliest radio modulation techniques. The receivers used to listen to AM-DSB-C are perhaps the simplest receivers of any radio modulation technique; which may be why that version of amplitude modulation is still widely used today.

Study of generation and detection of Amplitude Modulated signal. AIM OF THE EXPERIMENT: Generation of different types of signals-sinusoidal, square. Fig. 1: Amplitude Modulation Waveform. MIET/ECE/www.doorway.ru-I/ (c) AM Signal. (b) Modulating Signal. (a) Carrier Signal. MIET, ECE. K is a constant called the amplitude sensitivity of the modulator. The demodulation circuit is used to recover the message signal from the incoming AM wave at.
