:Is there a source for "It is the same code as the one described in differential Manchester encoding"? Am I missing something obvious by seeing them as different encodings? [[User:PaulT2022|PaulT2022]] ([[User talk:PaulT2022|talk]]) 03:49, 28 March 2023 (UTC)
::Our [[frequency modulation encoding]] article describes each data bit as being encoded by two time windows, with a single signal transition possible per window, and with the encoding of the bit determined by whether one or two transitions happen in these two windows. So does our [[differential Manchester encoding]] article. Do you think that one of these two descriptions is incorrect? Which one, and why? —[[User:David Eppstein|David Eppstein]] ([[User talk:David Eppstein|talk]]) 03:55, 28 March 2023 (UTC)
:::You're right! I was confused by wording of the [[Differential Manchester encoding]] article and assumed it refers to differential transmission of regular (biphase-level) Manchester code. The first sentence of its lead is ambiguous and can apply to either.
:::Compare what article says currently with how it's defined in Horowitz and Hill, for example: {{tq|the bit value is encoded as presence or absence of a mid-cell transition, following a mandatory transition at the beginning}}.
