Any device for changing analog signals into digital transmission—for example, recording someone singing onto a CD. The pressure waves in the air produced by the vibration of the person’s vocal chords are analog in form and continually vary in strength within a certain range of values.
The recording equipment samples this continually varying information at discrete time intervals and converts it to digital form.
Analog-to-digital converters (ADCs) are used in industry to convert environmental variables (temperature, pressure, density, speed, and so on) that vary continuously over time to digital information, which can then be analyzed using computer programs. ADCs are used in analog modems to convert digital signals into audio and vice versa. To buy this type of device from Amazon just click here.
