Signals are subjected to various operations in the time-domain in electrical circuits and
systems. Some of the basic signal operations are scaling by a constant, differentiation,
integration, multiplication by another signal (this is called time-domain modulation),
delaying or advancing in time, etc. When a signal undergoes a time-domain operation, its
Fourier transform undergoes a corresponding operation in the frequency-domain. We want
to establish this correspondence through the study of properties of Fourier transforms. We
cover some basic properties of Fourier transforms in this section and continue ...
