However, analog communication systems also have some disadvantages:
Digital communication systems use discrete signals to transmit information. These systems are widely used in computer networks, digital telephony, and satellite communication. The advantages of digital communication systems include:
Analog communication systems are used to transmit continuous-time signals, such as audio, video, and images. These systems use analog modulation techniques, such as amplitude modulation (AM), frequency modulation (FM), and phase modulation (PM), to encode the information signal onto a carrier wave. The modulated signal is then transmitted through a channel or medium to the receiver.
