Abstract
A cross-level digital signal transmission device between two systems for cross-level digital signal transmission. Bi-directional symmetrical transmission is achieved without using additional control signals, and use of the transmission signal itself eliminates the positive feedback loop. Thus, neither additional control signals nor resulting unsymmetrical circuits need be provided.
