81Milgram experiment — For Milgram s other well known experiment, see Small world experiment. The experimenter (E) orders the teacher (T), the subject of the experiment, to give what the latter believes are painful electric shocks to a learner (L), who is actually an… …
82Analog sound vs. digital sound — Analog sound versus digital sound compares the two ways in which sound is recorded and stored. Actual sound waves consist of continuous variations in air pressure. Representations of these signals can be recorded in either digital or analog… …
83Differential TTL — is a type of binary electrical signaling based on the TTL (transistor transistor logic) standard. Normal TTL signals are single ended, which means that each signal consists of a voltage on one wire, referenced to a system ground. The low voltage… …
84Air-fuel ratio meter — An air fuel ratio meter monitors the air fuel ratio of an internal combustion engine. Also called air fuel ratio gauge, air fuel meter, or air fuel gauge. It reads the voltage output of an oxygen sensor, sometimes also called lambda sensor,… …
85Clamp (circuit) — A clamp or clamp circuit is an electrical circuit used to prevent another circuit from exceeding a certain predetermined voltage level. It operates by sensing the output voltage of the monitored circuit and then as the output voltage approaches… …
8678xx — The 78xx (also sometimes known as LM78xx) series of devices is a family of self contained fixed linear voltage regulator integrated circuits. The 78xx family is a very popular choice for many electronic circuits which require a regulated power… …
87Earth leakage circuit breaker — An Earth Leakage Circuit Breaker (ELCB) is a safety device used in electrical installations with high earth impedance to prevent shock.PurposeMany electrical installations have a relatively high earth impedance. This may be due to the use of a… …
88Logic gate — A logic gate is an idealized or physical device implementing a Boolean function, that is, it performs a logical operation on one or more logic inputs and produces a single logic output. Depending on the context, the term may refer to an ideal… …
89Transmitter — For biologic transmitters, see transmitter substance. Commercial FM broadcasting transmitter at radio station WDET FM, Wayne State University, Detroit, USA. It broadcasts at 101.9 MHz with a radiated power of 48 kW. In electronics and… …
90Cockcroft-Walton generator — The Cockcroft Walton (CW) generator, or multiplier, was named after the two men who in 1932 used this circuit design to power their particle accelerator, performing the first artificial nuclear disintegration in history. John Douglas Cockcroft… …
