Digital electronics

Electronics that work with digital signals. In contrast, analog circuits deal with analog signals whose performance depends more on manufacturing tolerance, signal attenuation, and noise. Numerical techniques are useful because it is much easier to get an electronic device to navigate through one of many known situations than to accurately represent a continuous range of values.
