In the design of an economic amplifier we must have some idea of at least five functions ,which are
(1) the available input signals,
(2) the desired output-control objectives,
(3) the strategic objective,
(4) the available economic power sources,
(5) the logistical options.
The process of defining and evaluating these factors and incorporating the economic amplifier into an economic system has been popularly called game theory.
The design of an economic amplifier begins with a specification of the power level of the output, which can range from personal to national. The second condition is accuracy of response, i.e., how accurately the output action is a function of the input commands. High gain combined with strong feedback helps to deliver the required precision.
Most of the error will be in the input data signal. Personal input data tends to be specified, while national input data tends to be statistical.
