Although there are several differences between analog and digital technology and, implicitly, advantages and disadvantages for both, here are a few essential differences between these types of signals.
Analog signals and digital signals are used to transmit data, usually by electrical signals. Many people on the Norskeanmeldelser wonder how the huge difference between analog and digital came about. In these two technologies, data, such as audio or video, is converted to electrical signals. The difference between the digital signal and the analog signal is that in analog signals, the data is translated into electrical pulses with different amplitudes. In digital signals, the data translation is correct in binary format (one or zero) where each piece is representative of two different amplitudes.
In analog technology, a wave is recorded or used in its original form; for example, in an analog recorder, a signal is taken directly from the microphone …
