Small analog to digital converter box full#
In the above example of an eight-bit ADC, an error of one LSB is 1/256 of the full signal range, or about 0.4%. These errors are measured in a unit called the least significant bit (LSB). Quantization error and (assuming the ADC is intended to be linear) non-linearity are intrinsic to any analog-to-digital conversion. AccuracyĪn ADC has several sources of errors. These nonlinearities introduce distortion that can reduce the signal-to-noise ratio performance of the ADC and thus reduce its effective resolution. Important parameters for linearity are integral nonlinearity and differential nonlinearity. These errors can sometimes be mitigated by calibration, or prevented by testing. NonlinearityĪll ADCs suffer from nonlinearity errors caused by their physical imperfections, causing their output to deviate from a linear function (or some other function, in the case of a deliberately nonlinear ADC) of their input.

The recording equipment samples this continually varying information at discrete time intervals and converts it to digital form.Īnalog-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.
