Complex Conjugation in the Continuous Time

AI Thread Summary
Taking the complex conjugation of a continuous time signal, such as a sinusoidal signal, is mathematically valid and can be done before sampling. The physical correctness of this operation depends on the context and representation of the complex numbers involved. If the complex numbers represent modulated signals, their conjugation can be useful for processing, especially in signal recovery. However, the implications of this operation should be carefully considered in relation to the specific application. Ultimately, the feasibility of complex conjugation in this context is supported by mathematical principles, but its practical implications must be evaluated based on the signal's characteristics.

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?

Thanks

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.
 
So I know that electrons are fundamental, there's no 'material' that makes them up, it's like talking about a colour itself rather than a car or a flower. Now protons and neutrons and quarks and whatever other stuff is there fundamentally, I want someone to kind of teach me these, I have a lot of questions that books might not give the answer in the way I understand. Thanks
