For quasi-constant weight codes the conditions of undetected errors and their multiplicity at influence of noise in a transmission channel or occurring faults in devices are determined in the paper. The formula of the undetected error probability for a quasi-constant weight code, which depends on an error probability of bit-by-bit crossings, type and multiplicity of errors are obtained. The results of the researches make it possible to determine the fields of effective application for the given types of codes at designing digital units with error detection ability.
Keywords: quasi-constant weight code, constant weight code, error detection ability, undetected error probability
