I want to transmit digital signals over an existing electrical network. Can someone give me an idea of how to go about it?
Analog signals are continuous and can take on any value within a range, while digital signals are discrete and can only take on specific values, typically represented as 0s and 1s.
Digital signals are typically transmitted over long distances using fiber optic cables or wireless communication technologies such as satellite or cellular networks.
Digital signals are less susceptible to noise and interference, can be easily processed and manipulated, and can carry more information compared to analog signals.
Modulation is the process of converting digital signals into analog signals in order to transmit them over a physical medium. This allows for the signals to travel longer distances without losing their integrity.
Some common methods of encoding and decoding digital signals include amplitude shift keying (ASK), frequency shift keying (FSK), and phase shift keying (PSK). These methods convert digital signals into different analog waveforms that can be transmitted and then converted back into digital signals at the receiving end.
