46Digital versus film photography — has been a topic of debate since the invention of digital cameras towards the end of the 20th Century. Both digital and film photography have advantages and drawbacks.[1][2] 21st century photography is dominated by digital operation, but the… …
47Flow measurement — is the quantification of bulk fluid movement. Flow can be measured in a variety of ways. Positive displacement flow meters acumulate a fixed volume of fluid and then count the number of times the volume is filled to measure flow. Other flow… …
48Thermoelectric cooling — uses the Peltier effect to create a heat flux between the junction of two different types of materials. A Peltier cooler, heater, or thermoelectric heat pump is a solid state active heat pump which transfers heat from one side of the device to… …
49Jitter — For other meanings of this word, see Jitter (disambiguation). Jitter is the undesired deviation from true periodicity of an assumed periodic signal in electronics and telecommunications, often in relation to a reference clock source. Jitter may… …
50Ruido de Johnson-Nyquist — Saltar a navegación, búsqueda El ruido de Johnson–Nyquist (ruido térmico, ruido de Johnson, o ruido de Nyquist) se genera por la agitación térmica de los portadores de carga (generalmente electrones dentro de un conductor) en equilibrio, lo que… …
