Mechanical filter — Figure 1. A mechanical filter made by the Kokusai Electric Company intended for selecting the narrow 2 kHz bandwidth signals in SSB radio receivers. It operates at 455 kHz, a common IF for these receivers, and is dimensioned 45×15×15 mm ( … Wikipedia
Superheterodyne receiver — A 5 tube superheterodyne receiver made in Japan around 1955 In electronics, a superheterodyne receiver (sometimes shortened to superhet) uses frequency mixing or heterodyning to convert a received signal to a fixed intermediate frequency, which… … Wikipedia
Prototype filter — Prototype filters are electronic filter designs that are used as a template to produce a modified filter design for a particular application. They are an example of a nondimensionalised design from which the desired filter can be scaled or… … Wikipedia
Horn speaker — A horn speaker is a loudspeaker which uses a horn to increase the overall efficiency of the driving element, typically a diaphragm driven by an electromagnet. The horn itself is a passive component and does not amplify the sound from the driving… … Wikipedia
Cutoff frequency — This article is about signal processing. For other uses, see Cutoff (disambiguation). Magnitude transfer function of a bandpass filter with lower 3 dB cutoff frequency f1 and upper 3dB cutoff frequency f2 … Wikipedia
Subwoofer — A subwoofer is a woofer, or a complete loudspeaker dedicated to the reproduction of bass audio frequencies, from perhaps 150 Hz down as far as 20 Hz, or in rare cases lower. Also known as subs , these are used to augment the low frequency… … Wikipedia
Förster resonance energy transfer — (abbreviated FRET), also known as Fluoresence resonance energy transfer or resonance energy transfer (RET), describes an energy transfer mechanism between two chromophores. A donor chromophore in its excited state can transfer energy by a… … Wikipedia
Radio transmitter design — In plate modulation systems the voltage delivered to the stage is changed. As the power output available is a function of the supply voltage, the output power is modulated. This can be done using a transformer to alter the anode (plate) voltage.… … Wikipedia
Loudspeaker enclosure — A loudspeaker enclosure is a cabinet designed to transmit sound to the listener via mounted loudspeaker drive units. The major role of the enclosure is to prevent the out of phase sound waves from the rear of the speaker from combining with the… … Wikipedia
Charles E. Smith (engineer) — Dr. Charles E. Smith was professor and Chair in the Department of Electrical Engineering at the University of Mississippi. His focus research areas included: application of electromagnetic theory to microwave circuits, application of numerical… … Wikipedia
Audio crossover — A passive 2 way crossover designed to operate at loudspeaker voltages Audio crossovers are a class of electronic filter used in audio applications. Most individual loudspeaker drivers are incapable of covering the entire audio spectrum from low… … Wikipedia
