Communication Systems in ECE                            



                          In Electronics and Communication Engineering (ECE), communication systems refer to the technologies and processes that enable the transmission and reception of information between two or more points. These systems encompass various elements such as transmitters, receivers, communication channels, and protocols to convey data efficiently, securely, and reliably.

                                  Communication systems are used across multiple mediums like wireless (radio waves, satellite), wired (optical fibers, coaxial cables), and hybrid (Wi-Fi, 5G). They form the backbone of modern communication, enabling technologies like telephony, internet, satellite broadcasting, and more.
