Complex Conjugation in the Continuous Time

  1. Nov 20, 2013 #1
    Hello all,

    I have a continuous time signal v(t), and mathematically I want to take the complex conjugation of it for processing purposes, but I am not sure if this is physically correct. Is it?

    Is v a complex variable?

    Its discrete time samples are, but I want to take the conjugation before sampling. Is it correct physically speaking?

    All you've told us is that you have some complex numbers. Whether or not any operation on those numbers is "physically correct" will depend on what those numbers represent.

    I have some complex numbers which are modulated into a continuous sinusoidal signal. Usually, these numbers are recovered by demodulation of the noise-free signal. I want to know if taking complex conjugation of a continuous time signal, like a sinusoidal signal, is possible in reality.
