Non-return-to-zero

Index Non-return-to-zero

In telecommunication, a non-return-to-zero (NRZ) line code is a binary code in which ones are represented by one significant condition, usually a positive voltage, while zeros are represented by some other significant condition, usually a negative voltage, with no other neutral or rest condition.

Asynchronous communication

In telecommunications, asynchronous communication is transmission of data, generally without the use of an external clock signal, where data can be transmitted intermittently rather than in a steady stream.

Bandwidth (signal processing)

Bandwidth is the difference between the upper and lower frequencies in a continuous band of frequencies.

Binary number

In mathematics and digital electronics, a binary number is a number expressed in the base-2 numeral system or binary numeral system, which uses only two symbols: typically 0 (zero) and 1 (one).

Bipolar encoding

In telecommunication, bipolar encoding is a type of return-to-zero (RZ) line code, where two nonzero values are used, so that the three values are +, −, and zero.

Bit

The bit (a portmanteau of binary digit) is a basic unit of information used in computing and digital communications.

Bit rate

In telecommunications and computing, bit rate (bitrate or as a variable R) is the number of bits that are conveyed or processed per unit of time.

Bit slip

In digital transmission, bit slip is the loss or gain of a bit or bits, caused by clock drift – variations in the respective clock rates of the transmitting and receiving devices.

Bit stuffing

In data transmission and telecommunication, bit stuffing (also known—uncommonly—as positive justification) is the insertion of non information bits into data.

Data signaling rate

In telecommunication, data signaling rate (DSR), also known as gross bit rate, is the aggregate rate at which data pass a point in the transmission path of a data transmission system.

DC bias

When describing a periodic function in the time domain, the DC bias, DC component, DC offset, or DC coefficient is the mean amplitude of the waveform.

E-NRZ-L

In telecommunication, an enhanced-non-return-to-zero-level (E-NRZ-L) line code is a binary code in which 1s are represented as low level and 0s are represented as high level condition with no other neutral or rest condition, similar to Non-return-to-zero; However, the major enhancement over NRZ is the addition of a parity bit (usually odd parity) to the end of the bit stream.

In logic, an inverse is a type of conditional sentence which is an immediate inference made from another conditional sentence.

Line code

Some signals are more prone to error than others when conveyed over a communication channel as the physics of the communication or storage medium constrains the repertoire of signals that can be used reliably.

Manchester code

In telecommunication and data storage, Manchester code (also known as phase encoding, or PE) is a line code in which the encoding of each data bit is either low then high, or high then low, for equal time.
