| In this lab activity we will use the [[http://www.analog.com/en/design-center/evaluation-hardware-and-software/evaluation-boards-kits/adalm1000.html|ADALM1000]] to introduce amplitude modulation (AM) and envelope detection demodulation. A signal's envelope is equivalent to its outline, and an envelope detector connects the amplitude peaks of the signal. [[university:courses:electronics:text:chapter-7#envelope_detector|Envelope detection]] has numerous applications in the fields of signal processing and communications, one of which is amplitude modulation (AM) detection or demodulation. | In this lab activity we will use the [[adi>en/design-center/evaluation-hardware-and-software/evaluation-boards-kits/adalm1000.html|ADALM1000]] to introduce amplitude modulation (AM) and envelope detection demodulation.

| Amplitude modulation (AM) is a modulation technique used in electronic communication, most commonly for transmitting information via a radio frequency carrier wave. In amplitude modulation, the amplitude (signal strength) of the carrier wave is varied in proportion to the waveform being transmitted. That waveform may, for instance, correspond to the sounds to be reproduced by a loudspeaker, or the light intensity of television pixels. | Amplitude modulation (AM) is a modulation technique used in electronic communication, most commonly for transmitting information via a radio frequency carrier wave.
