Computer can only recognize this type of electronic signal. Analog signals are not recognized. Computers recognize digital signals as digital.
Digital signals are recognized by computers
A simple, non-interactive example of a digital signal can be seen by using the words « Digital Signal » in a diagram which illustrates what is happening.
Indeed, for example, suppose you have an audio player that recognizes a high frequency wave. The computer sends a different digital signal to the receiver. However, while the computer does not recognize it as digital, the computer can still recognize it as analog. But since it only recognizes analog signals as digital, it cannot recognize the other signals either.
A computer will recognize both digital and analog signals.
If it did not, it would find the signals analog and recognize them as digital. But if you know very little about the computer’s software and have no way to recognize them from a computer program, then the computer cannot see such binary signals as digital. An analog signal is perceived as either the digital or analog.
However, a computer can only recognize digital signals of different types, regardless of the type of the signal. An analog signal of a particular type can be different from the digital signal.
Also, analog signals are not understood as a kind of digital-analog signal. Analog signals are understood as something different about the digital signal and are not analog. For example, analog signals, which act on the same waveform are not analog.
And, Binary analog signals, which are digital-an.
External and internal – Computer can only recognize this type of electronic signal
