“Approximation for Root( I2 + Q2),” J.A. Crawford.

“Computation of Square Roots,” J.A. Crawford .

“Optimum Eigenfilter Design Methodology,” J.A. Crawford.

“Computing Data Windows Recursively,” J.A. Crawford. Discusses simple numerical means suitable for DSP implementation for computing Gaussian and Blackman data windows. Method can be easily extended to many other window types.
