Digital transmission refers to the process of sending data in the form of discrete signals, typically represented as binary code (0s and 1s). This method allows for more efficient and reliable communication over various media, such as fiber optics, copper wires, or wireless networks. Digital signals are less susceptible to noise and interference, making them ideal for transmitting information over long distances. In digital transmission, data is encoded into a format suitable for the transmission medium. Techniques like pulse code modulation (PCM) and quadrature amplitude modulation (QAM) are commonly used to convert analog signals into digital form. This conversion enables clearer and faster communication, which is essential for applications like internet browsing, video streaming, and telecommunications.
