PURPOSE:To eliminate the noise of a transformer type encoder by selecting two optional arrays among arrays of respective digits of a ternary code, and performing mutual winding operation according to arrays determined so that the AND result among terms of the respective arrays is 0. CONSTITUTION:Eight sense loops S0-S7 are given to the phase coordinates in a binary representation (parenthesized in a figure). Input branch transformers T0-T7 which use ring cores are provided in corresponding to the sense loops S0-S7, and the primary windings W10-W17 of the respective input branch transformers and the sense loops are connected together. Then, the respective input branch transformer are provided with the secondary windings W21-W32 as many as digits displayed by, for example, ''1'' in the binary representation of position coordinates of the corresponding sense loops S0-S7. Then, the output windings W33-E35 are provided as the secondary windings of output composite transformers T8-T10 and a composite signal is outputted. |
