Explain the physical meaning of imgpart of signal

Click For Summary
SUMMARY

The discussion clarifies that the imaginary part of a signal does not possess a physical meaning but is instead dependent on the relative phase with respect to another signal. It is established that in signal processing, the cosine component is typically regarded as the real part, while the sine component is viewed as the imaginary part. This distinction is crucial for understanding signal representation in the complex plane.

There is no physical meaning. It just depends on the relative phase (relative to some other signal).
 
As the previous responder said, it is just the phase. Usually a cos is considered real and a sin is considered imaginary.
