Abstract : The object of the invention is a method of measuring the coding error of coders with parallel output and cyclic code is different in that, to increase the rate of measuring the error and to directly obtain the mean or root-mean-square error, a standard sawtooth voltage is periodically fed to the input of the coder and on the output replacement instants of the coded combinations are compared with a standard sequence of pulses that are synchronized with the standard sawtooth voltage and pulses are distinguished that are proportional, in duration and sign, to the coder error at separate points of the coding, and double integration or one-sided inversion with double integration produces the mean or the root-mean-square error of the coder, which is recorded by an indicator.
