While Communication Systems is a robust text, the field of telecommunications has shifted significantly toward software-defined radio (SDR), 5G, and IoT protocols.
Communication systems are designed to transmit information from a source to a destination through a communication channel. The source can be a human being, a machine, or a device, while the destination can be another human being, machine, or device. The communication channel can be a wire, fiber optic cable, radio wave, or any other medium that can transmit information.
