signal and communications systems

Signal and communication systems involve sending information from one place to another using various methods such as electrical, optical, or wireless signals. Signals carry data, like voice, video, or digital information, through channels like cables, airwaves, or fiber optic lines. These systems process, encode, transmit, and receive signals efficiently and accurately, ensuring the intended message reaches its destination with minimal loss or distortion. They form the backbone of modern communication, enabling everything from phone calls and internet browsing to television broadcasting and satellite communications.
