Coding system for time stacked signals and direction of transition - uses 3 bits code words denoting condition of original period and possible transition

摘要

Coding system for time stacked signals and direction of transition between two states. The signals are then decoded into the transformed states. It comprises a transmission side, a scanning circuit, a coding circuit and a shift register (6). The scanning circuit operates at a fixed repetition frequency on the input. The coding circuit converts the signal in the time stack into a code word formed by a number of bits. The code word is taken up in the shift register before it is transmitted. It contains 3 bits (a, b, c) with the condition of the original signal in the first bit and the period and possible transition in the other two bits.
