Biphase or Bi-phase may refer to: * Biphase modulation, or binary phase-shift keying *

Differential Manchester encoding Differential Manchester encoding (DM) is a line code in digital frequency modulation in which data and clock signals are combined to form a single two-level self-synchronizing data stream. In various specific applications, this method is also call ...
