Popis: This report describes the circuit design of a new hybrid analogdigital statistical averaging computer used to calculate statistical averages of analog voltages presented to it. The unit, with a dynamic range of +/- 10 volts, an acucracy of +/- 0.25 percent, and a maximum speed of 1000 samples per second, is particularly well suited for use with modern high-speed iterative analog computers. The output is primarily visual, but electrical signals are also available for use by digital computers, printers, punches, and the like. Circuit simplifications have resulted in an inexpensive unit which requires few adjustments. Digital storage of sums eliminates the drift present in pure analog averaging schemes if the summation time is long.
