Unformatted text preview: AM-DSB vs. AM-SSB: A team project.Preparation1. Download 6 different wav filesx1.wav, x2.wav, x3.wav, x4.wav,x5.wav, x6.wav2. Download the ece301conv.mfile. 3. Open MATLAB and change the directory to where you have saved the previous files.4. Enter the following commands:duration=8;f_sample=44100; t=(((0-4)*f_sample+0.5):((duration-4)*f_sample-0.5))/f_sample;5. Load x1(t) by the commands [x1, f_sample, N]=wavread('x1');x1= x1';6. Load other x2(t) to x6(t) similarly.Please go through steps in the prerequisite experimentif you have not tried it before.Goals:1. You are allowed to only use frequency band 0-8kHz. The first goal is to squeeze in 3 different signals x1(t) to x3(t) using AM-DSB. Each signal has to be pre-filtered to have a bandwidth 1kHz. You need to design the carrier frequencies of this system.2. The second goal is to squeeze in 6 different signals x1(t) to x6(t) using AM-SSB. Each signal has to be pre-filtered to have a bandwidth 1kHz. You need to design the carrier frequencies of this system and also pre-filtered to have a bandwidth 1kHz....
