Detailed explanation-1: -Whereas baseband uses digital signaling, broadband uses analog signals in the form of optical or electromagnetic waves over multiple transmission frequencies. For signals to be both sent and received, the transmission media must be split into two channels.
Detailed explanation-2: -Broadband Transmission sends data in the form of analog signals, allowing signals to be sent at multiple frequencies simultaneously. This broadband transmission is unidirectional. In other words, the data is only transmitted in one direction at the same time.
Detailed explanation-3: -Is WiFi digital or analog? Signals are neither analog nor digital because they are simply waves of information. It’s the way they are encrypted that makes them analog or digital. So, in this way, WiFi technology sends information in digital form.
Detailed explanation-4: -An analog signal is a voltage, current, or physical quantity that continuously and infinitely varies in accordance with some time-varying parameter. For example, radio waves, television waves, or sound waves are all examples of analog signals.
