Complex Signals - DTU
where x∗(t) is the complex conjugate of x(t), and (↔) denotes a Fourier trans-form pair. Let the complex signal x(t) be expressed in the form: x(t) = x 1(t)+jx 2(t), (2.8) where x 1(t) and x 2(t) are real signals. Let their spectra be X 1(f) and X 2(f), respectively, i.e. x 1(t) ↔ X 1(f) and x 2(t) ↔ X 2(f). The real part of x(t) can be ...

For a time-harmonic signal on a transmission line, one can analyze the problem in the frequency domain using phasor technique. A phasor variable is linearly proportional to a Fourier transform variable. The telegrapher’s equations (11.1.6) and (11.1.7) then become d dz V(z;!) = j!LI(z ...

This analysis will neither introduce spurious effect, nor miss important features. Since both representations are equivalent, it is just a matter of which of the representations makes the identification of patterns easier.
