Abstract :
This paper describes a chart and a mechanization of the chart in the form of a calculator that will simplify the calculation of the effects of feedback. When the magnitude and phase of the feedback are put into the calculator, figures are obtained at each frequency point for the magnitude and phase shift of the transfer characteristic with the feedback loop closed.
