Dynamic Accuracy and Error in Analog Computations

It is shown that a simple circle diagram can be developed which will readily convert the dynamic amplitude ratio and phase shift characteristics of analog computing units (or similar electronic devices) into the corresponding rms-error functions. These rms-error functions which directly conform with the static dc accuracy specifications generally used, can be plotted in a new diagram giving the operational error characteristics of the units. By the use of this error diagram the signal frequency bands can be determined which will give satisfactory dynamic operations of the analog computing units within given error limits.
