EXPERIMENT NO. 2 . AM Transmission - Envelop Detector OBJECTIVE: The activity aims: To describe AM reception. To understand how signals behave in Amplitude Modulation with different parameter changes. EQUIPMENT REQUIREMENT Internet connection and browser Laptop with Windows Installed JRE software 2. Now that you are familiar with the envelope detection analyze what happens when one of the following parameters is changed: Change Effect on demodulated signal Increase the modulation index to m=4 -Take screenshots of demodulated signal with monginal setting & Switch off the carriers ? ? - Take screenshots of demodulated signal without carriers Change the carrier frequency to 60kHz Take screenshots of demodulated Signal with carrier frequency to 60kHz Change phase of the carrier to 60 - Take screenshot of demodulated signal with carrier phase of 60" AM is inefficient in power usage as most of the power is consumed by the carrier signal. But it conveys none of the original information. Measure the power of the total transmission signal and the shares taken by the carrier and the two sidebands. Take a look at other alternative AM demodulation technique. Research on the ff. Synchronous detector. Envelope detector Crystal radio INTERPRETATION OF DATA THANK YOU!!
