random frequency noise
31Signal noise — In science, and especially in physics and telecommunication, noise is fluctuations in and the addition of external factors to the stream of target information ( signal ) being received at a detector. In communications, it may be deliberate as for …
32Active noise control — (ANC) (also known as noise cancellation, active noise reduction (ANR) or antinoise) is a method for reducing unwanted sound. Contents 1 Explanation 2 Applications 3 See also 4 …
33Radio-frequency identification — (RFID) is a technology that uses radio waves to transfer data from an electronic tag, called RFID tag or label, attached to an object, through a reader for the purpose of identifying and tracking the object. Some RFID tags can be read from… …
34Radio-frequency sweep — or Frequency sweep or RF sweep refer to scanning a radio frequency band for detecting signals being transmitted there. This is implemented using a radio receiver having a tunable receiving frequency. As the frequency of the receiver is changed to …
35white noise — noun a noise produced by a stimulus containing all of the audible frequencies of vibration white noise is a good masking agent • Hypernyms: ↑noise, ↑interference, ↑disturbance * * * noun Etymology: so called from the analogy of its composition to …
36Timeline of thermodynamics, statistical mechanics, and random processes — A timeline of events related to thermodynamics, statistical mechanics, and random processes. Ancient times *c. 3000 BC The ancients viewed heat as that related to fire. The ancient Egyptians viewed heat as related to origin mythologies. One… …
37white noise — 1. Also called white sound. a steady, unvarying, unobtrusive sound, as an electronically produced drone or the sound of rain, used to mask or obliterate unwanted sounds. 2. Physics. random noise with a uniform frequency spectrum over a wide range …
38Static random access memory — (SRAM) is a type of semiconductor memory where the word static indicates that, unlike dynamic RAM (DRAM), it does not need to be periodically refreshed, as SRAM uses bistable latching circuitry to store each bit. SRAM exhibits data remanence,cite …
39white noise — noun a) A random signal (or process) with a flat power spectral density; a signal with a power spectral density that has equal power in any band, at any centre frequency, having a given bandwidth. Conventional statistica …
40White noise — White noise, n. a mixture or random noise sounds extending over the entire audible frequency spectrum with approximately equal intensity at all frequencies. It is used in certain experiments, as in psychology, to prevent subjects from hearing… …
