Making Sense of Effective Bits in Oscilloscope Measurements

When considering oscilloscope or digitizer performance, the term "Effective Number
of Bits" (ENOB or effective bits) is often used, but it seems seldom fully appreciated
or understood, especially in terms of what it means to real-world signals and
measurements. In this paper, we will describe effective bits in terms that are useful
in better understanding the real world implications.
