In this paper we consider binary codes with summation used at designing test systems of combinational logical circuits. We offer new codes, determine their properties and compare these codes with each other.
The article provides the properties of the family of sum codes with on-data bits and one weighted data bit concerning the error detection in data vectors. In comparison with classic Berger codes, the described weighted and modular weighted sum codes have improved error detection characteristics. Also, weighted sum codes, as well as Berger codes, detect any… (More)
