    en.wikipedia.org/wiki/Return-to-zero

    Return-to-zero (RZ or RTZ) describes a line code used in telecommunications signals in which the signal drops (returns) to zero between pulses. This takes place even if a number of consecutive 0s or 1s occur in the signal. The signal is self-clocking. This means that a separate clock does not need to be sent alongside the signal, but suffers ...

    1337 number, as represented in bipolar encoding, known as AMI (Alternate mark inversion), where : 1337 10 = 10100111001 2. 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.

    en.wikipedia.org/wiki/Non-return-to-zero

    Non-return-to-zero, inverted (NRZI, also known as non-return to zero IBM, [1] inhibit code, [2] or IBM code [2]) was devised by Bryon E. Phelps in 1956. [ 2 ] [ 3 ] It is a method of mapping a binary signal to a physical signal for transmission over some transmission medium.

  5. Hybrid ternary code - Wikipedia

    en.wikipedia.org/wiki/Hybrid_ternary_code

    In telecommunications, the hybrid (H-) ternary line code is a line code that operates on a hybrid principle combining the binary non-return-to-zero-level (NRZL) and the polar return-to-zero (RZ) codes. The H-ternary code has three levels for signal representation; these are positive (+), zero (0), and negative (−).

    Non-return-to-zero level. This is the standard positive logic signal format used in digital circuits. forces a high level forces a low level NRZ–M: Non-return-to-zero mark forces a transition does nothing (keeps sending the previous level) NRZ–S: Non-return-to-zero space does nothing (keeps sending the previous level) forces a transition RZ

  7. Unipolar encoding - Wikipedia

    en.wikipedia.org/wiki/Unipolar_encoding

    NRZ (Non-Return-to-Zero) - Traditionally, a unipolar scheme was designed as a non-return-to-zero (NRZ) scheme, in which the positive voltage defines bit 1 and the zero voltage defines bit 0. It is called NRZ because the signal does not return to zero at the middle of the bit, as instead happens in other line coding schemes, such as Manchester ...

    United Wholesale Mortgage (UWM), with billionaire Mat Ishiba at the helm, has launched a new zero-percent down mortgage program. This program allows qualified buyers to finance 97% of their home's ...

  9. Modified AMI code - Wikipedia

    en.wikipedia.org/wiki/Modified_AMI_code

    At the North American T2 rate (6.312 Mbit/s), bipolar violations are inserted if 6 or more consecutive zeros occur. This line code is called bipolar with six-zero substitution (B6ZS), and replaces 6 consecutive zeros with the pattern "0VB0VB". Depending on the polarity of the preceding mark, that could be 0+−0−+ or 0−+0+−.
