AM transmission - envelope detector

    Start To launch labAlive simulation applications you need a Java Runtime Environment supporting Java Web Start on your system. Here you can get more information about installing the right Java version.
AM transmission - envelope detector
AM speech transmission with envelope detection - audio live demo. This app is optimized for audio playback.
Transmitted signal with envelope - Double-sideband amplitude modulation DSB-AM
AM received signal spectrum
The speech audio signal shapes the envelope of the carrier wave. Received signal spectrum .

Start

Listen to the audio speech signal that is envelope detected after AM transmission. The audio playback starts automatically when the app is launched.


Experiment

How does it sound when the modulation index is increased or even the carrier is switched off?

Figure out why a carrier frequency of 10981.91214 Hz was chosen!
