Three Radio Theremin
The Three Radio Theremin was originally created by Tomoya Yamamoto . The theremin is constructed by tuning 3 separate radios to create a system that acts similar to a stand-alone theremin. The circuitry in each individual radio is used to functionally modulate the sound out of the third, producing similar tonal qualities as a theremin. The following process can be used to produce the same effect: # Find 3 sets of Amplitude Modulated (AM) Radios of superheterodyne receiver A superheterodyne receiver, often shortened to superhet, is a type of radio receiver that uses frequency mixing to convert a received signal to a fixed intermediate frequency (IF) which can be more conveniently processed than the original carr ... type # Place set 3 radio between set1 and set 2 # Set 1 and Set 2 radios tuned to 1145 kHz and set 3 to 1600 kHz so that local oscillators of set 1 and 2 well received by set 3 radio # Local oscillator of set 1 and 2 may produce beat sound in set 3 # ...

Theremin
The theremin (; originally known as the ætherphone/etherphone, thereminophone or termenvox/thereminvox) is an electronic musical instrument controlled without physical contact by the performer (who is known as a thereminist). It is named after its inventor, Leon Theremin, who patented the device in 1928. The instrument's controlling section usually consists of two metal antenna (radio), antennas which sense the relative position of the thereminist's hands and control oscillation, oscillators for frequency with one hand, and amplitude (Loudness, volume) with the other. The electric signals from the theremin are amplifier, amplified and sent to a loudspeaker. The sound of the instrument is often associated with wikt:eerie, eerie situations. The theremin has been used in movie soundtracks such as Miklós Rózsa's ''Spellbound (1945 film), Spellbound'' and ''The Lost Weekend (film), The Lost Weekend'', Bernard Herrmann's ''The Day the Earth Stood Still (soundtrack), The Day the E ...

Amplitude Modulated
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. This technique contrasts with angle modulation, in which either the frequency of the carrier wave is varied, as in frequency modulation, or its phase, as in phase modulation. AM was the earliest modulation method used for transmitting audio in radio broadcasting. It was developed during the first quarter of the 20th century beginning with Roberto Landell de Moura and Reginald Fessenden's radiotelephone experiments in 1900. This original form of AM is sometimes called double-sideband amplitude modulation (DSBAM), because the standard method produces sidebands on either side of the carrier frequency. Single-sideband modulation uses bandpass filters to eliminate one of the sidebands and pos ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Superheterodyne Receiver
A superheterodyne receiver, often shortened to superhet, is a type of radio receiver that uses frequency mixing to convert a received signal to a fixed intermediate frequency (IF) which can be more conveniently processed than the original carrier frequency. It was long believed to have been invented by US engineer Edwin Armstrong, but after some controversy the earliest patent for the invention is now credited to French radio engineer and radio manufacturer Lucien Lévy. Virtually all modern radio receivers use the superheterodyne principle; except those software-defined radios using ''direct sampling''. History Heterodyne Early Morse code radio broadcasts were produced using an alternator connected to a spark gap. The output signal was at a carrier frequency defined by the physical construction of the gap, modulated by the alternating current signal from the alternator. Since the output frequency of the alternator was generally in the audible range, this produces an audible ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
