Cramer's Rule in Complex Frequency Domain.

  1. Feb 23, 2009 #1
    Does Cramer's rule work in frequency domain? For example, if we have to solve two simeltaneous equations, as in nodel analysis or mesh-current method, can we use Cramer's rule to solve em? Would this be an efficient method?

    Yes. The frequency domain is simply complex numbers, which is a field just like the real numbers.

    Not necessarily more efficient, but maybe easier with complex numbers if you are doing it by hand on two simultaneous equations. If you are using a calculator or matlab, then just use matrix math or rref(). They should both work, depending on whether or not your calculator can handle complex numbers.
