The power spectral density (PSD) of a random signal is given by: such as radio waves

Electronic communication refers to the transmission, reception, and processing of information through electronic means, such as radio waves, microwaves, or optical fibers. Communication systems, on the other hand, refer to the overall system that enables communication, including the transmitter, channel, receiver, and any other components that facilitate the communication process. or optical fibers.
