51Coil Noise — is a phenomenon in electronics which produces both undesirable audible sound, and electronic noise. Contents 1 Description 2 Devices Effected By Coil Noise 3 Reducing Coil Noise 4 …
52Clavichord — 1977 clavichord by Keith Hill, Op. 44 (Op. 28 reworked) Keyboard instrument Hornbostel–Sachs classification 314.122 4 8 (Simple chordophone with keyboard sounded by tangents) …
53Headphone amplifier — A headphone amplifier is a kind of audio amplifier designed particularly to drive headphones instead of loudspeakers. Most commonly they are found embedded in electronic devices such as integrated amplifiers, portable music players and… …
54Anechoic chamber — An anechoic chamber An anechoic chamber (an echoic meaning non echoing or echo free) is a room designed to stop reflections of either sound or electromagnetic waves. They are also insulated from exterior sources of noise. The combination of both… …
55Cromaclear — slot style. Notice the brick design as opposed to the normal dot trio design Mask close up Cromaclear is a CRT …
56Neutron-star oscillation — Asteroseismology studies the internal structure of our Sun and other stars using oscillations. These can be studied by interpreting the temporal frequency spectrum acquired through observations[1]. In the same way, the more extreme neutron stars… …
57Dimensionless quantity — In dimensional analysis, a dimensionless quantity or quantity of dimension one is a quantity without an associated physical dimension. It is thus a pure number, and as such always has a dimension of 1.[1] Dimensionless quantities are widely used… …
58Shock absorber — Gas damper A shock absorber is a mechanical device designed to smooth out or damp shock impulse, and dissipate kinetic energy. It is a type of dashpot. Contents …
59Impedance matching — In electronics, impedance matching is the practice of designing the input impedance of an electrical load (or the output impedance of its corresponding signal source) to maximize the power transfer and/or minimize reflections from the load.… …
