Description

The input values of this block are the rectangular componentsu_re and u_im of a phasor in two dimensions.This block calculates the length y_abs andthe angle y_arg of the polar representation of this phasor.

y_abs = abs(u_re + j*u_im) = sqrt( u_re² + u_im² )y_arg = arg(u_re + j*u_im) = atan2(u_im, u_re)

Ports
