However, the effective number of bits of a device is limited by noise. This varies depend-ing on the output word rate and the gain setting used. This parameter is specifi ed by some companies as effec-tive resolution. Analog Devices specifi es peak-to-peak resolution, which is the number of fl icker-free bits and is calculated differently from effective resolution.
