Digital circuits III: How to go from analog to digital and back again, or, how does your CD player work? Analog to Digital Conversion At the scale of interest for most engineering applications, and certainly for those encountered in this course, the outside world can be considered to be continuous and analog in form. Consequently, most measurements of physical quantities at this scale are also analog. Clearly, the analog signals from our measuring devices must be converted into digital form before all the very wonderful properties of the digital computer are available to us. This process is called discretisation, where quantities that are continuous functions of some variable (often time, or space coordinates) are sampled at discrete intervals, where the amplitude is converted from an analog voltage to a digital number, and the resulting digital sequence is used to approximate the true function.
