摘要:
A significant simplification of the computation circuits for positioning systems is achieved by the use of three-valued codes. The use of the odd radix makes it possible to provide a control system symmetrical to positive and negative quantities which relieves the necessity to complement digital information. The paper discusses the construction of suitable cyclic codes and gives the logical design for the necessary conversion logic. Design proposals for the remainder of the control system are also corporated.
