2. Amplitude modulation - Wikipedia

   en.wikipedia.org/wiki/Amplitude_modulation

   Amplitude modulation (AM) is a modulation technique used in electronic communication, most commonly for transmitting messages with a radio wave.In amplitude modulation, the amplitude (signal strength) of the wave is varied in proportion to that of the message signal, such as an audio signal.

3. Demodulation - Wikipedia

   en.wikipedia.org/wiki/Demodulation

   Demodulation is the process of extracting the original information-bearing signal from a carrier wave. A demodulator is an electronic circuit (or computer program in a software-defined radio) that is used to recover the information content from the modulated carrier wave. [1] There are many types of modulation, and there are many types of ...

4. Detector (radio) - Wikipedia

   en.wikipedia.org/wiki/Detector_(radio)

   A major category of AM demodulation technique involves envelope detection, since the envelope of an AM signal is the original signal. A diode detector is a type of simple envelope detector. It consists of a diode connected between the input and output of the circuit, with a resistor and capacitor in parallel from the output of the circuit to ...

   The Theory of Evolution is a book by English evolutionary biologist and geneticist John Maynard Smith, originally published in 1958 in time for 150th anniversary of the birth of Charles Darwin and the centenary of the publication of The Origin of Species the following year. It serves as a general introduction to the eponymous subject, intended ...

8. Single-sideband modulation - Wikipedia

   en.wikipedia.org/wiki/Single-sideband_modulation

   In other cases, it may be desirable to maintain some degree of compatibility with simple AM receivers, while still reducing the signal's bandwidth. This can be accomplished by transmitting single-sideband with a normal or slightly reduced carrier. This mode is called compatible (or full-carrier) SSB or amplitude modulation equivalent (AME). In ...

   Losev was the first to analyze this device, investigate the source of the light, propose a theory of how it worked, and envision practical applications. [63] He published his experiments in 1927 in a Russian journal, [ 65 ] and the 16 papers he published on LEDs between 1924 and 1930 constitute a comprehensive study of this device.
