Signal

/ˌɪnfərˈmeɪʃən ˈθiəri/

noun … “Mathematics of encoding, transmitting, and measuring information.”

/ˈʃænən ˈlɪmɪt/

noun … “Maximum reliable information rate of a channel.”

Shannon Limit, named after Claude Shannon, is the theoretical maximum rate at which information can be transmitted over a communication channel with a specified bandwidth and noise level, while achieving error-free transmission. Formally defined in information theory, it sets the upper bound for channel capacity (C) given the signal-to-noise ratio (SNR) and bandwidth (B) using the Shannon-Hartley theorem: C = B * log2(1 + SNR).

Key characteristics of the Shannon Limit include:

/ˈmaɪ.moʊ/

noun — "multiple antennas, one link, supercharged throughput."

/ˌɛs siː ˌɛf ˌdiː ˈeɪ.mə/

noun — "the uplink method that saves mobile power while sharing frequencies efficiently."

/ˌoʊ.fɪdˈeɪ.mə/

noun — "a technique that divides bandwidth into multiple subcarriers for simultaneous transmission."

/ˌɛs ˌsiː ˈɛl/

noun — "the clock line that keeps serial data in step."

SCL (Serial Clock) is the timing signal used in serial communication protocols, most prominently in I²C (I2C) interfaces, to synchronize the transmission and reception of data on the SDA (Serial Data) line. The SCL line ensures that each bit of data is sampled at the correct moment, allowing reliable communication between devices over a shared bus.

/diː ɛm ˈtiː/

noun — "splitting a signal into multiple channels for cleaner data."

DMT (Discrete MultiTone) is a modulation technique that divides a communication channel into multiple orthogonal subcarriers, each carrying a separate data stream. It is widely used in digital subscriber line (DSL) technologies, such as ADSL, to maximize bandwidth efficiency and reduce interference. By transmitting data simultaneously across multiple tones, DMT mitigates the effects of channel noise, crosstalk, and frequency-selective fading.

/feɪz ˌmɒd.jʊˈleɪ.ʃən/

noun — "encoding data by shifting the signal's phase."

/dʒiː ɛn ɛs ɛs/

noun — "satellites guiding your position anywhere on Earth."

/ˌɛf iː tiː/

noun — "transistors controlled by electric fields instead of currents."
