Digital modulation

Digital modulation is a technique that converts digital data into radio signals to transmit information wirelessly or over cables. It works by changing specific properties of a carrier wave—such as its amplitude, frequency, or phase—based on the digital bits (0s and 1s) being sent. This process allows digital information, like internet data or audio, to be efficiently encoded onto signals that can travel through various mediums. Digital modulation is fundamental for modern communication systems, ensuring data is transmitted accurately and reliably over long distances while enabling high-speed internet, mobile phones, and satellite communications.
