Why do we have to analyze systems in the Fourier domain?
Please explain the physical meaning of the frequency response of a system.
Please try to describe the frequency characteristics of more then systems in your daily life.
Can we realize a physical distortionless transmission system? What is the theoretical significance of the distortionless transmission system? And what is the realistic significance?
What frequency properties have we used to analyze signal modulation and demodulation?
