ABSTRACT:
A processor system apparatus and method for determining a square root of a particular value of a square of a parameter for use with an electronic circuit breaker system. The system comprises a signal processor or logic circuit for receiving and using at least one input signal to process and output at least one output signal, wherein the logic circuit is configured to determine a whole root of the square root of a particular value of the square of a parameter, wherein the logic circuit is configured to determine a slope of the square of a parameter bounded by at least a first point and a second point, where the first point corresponds to a first value of the square of a parameter and the second point corresponds to a second value of the square of a parameter, wherein the logic circuit is configured to determine a difference between the particular value of the square of a parameter and a value of a square of the whole root, wherein the logic circuit is configured to determine a fractional part of the square root of a particular value of the square of a parameter using the slope and the difference, wherein the logic circuit is configured to determine the square root by combining the whole root of the square root and the fractional part of the square root, and wherein the logic circuit outputs at least one output signal using the square root.
