Digital modulation is a technique used to encode digital information onto a carrier wave for transmission over various communication channels. This process involves altering specific properties of the carrier wave, such as its amplitude, frequency, or phase, to represent the digital data. Common types of digital modulation include Amplitude Shift Keying (ASK), Frequency Shift Keying (FSK), and Phase Shift Keying (PSK). The primary advantage of digital modulation is its ability to transmit data more efficiently and with greater resistance to noise and interference compared to analog methods. This makes it essential for modern communication systems, including cellular networks, Wi-Fi, and satellite communications.
