What this part means
The lower label selects a particular version, component, or indexed member of the quantity. For example, x₀ and xₜ can be values at different positions.
Its job in the formula
A subscript distinguishes a version, component, step, or member of a quantity. It does not automatically mean multiplication.

The passage around this formula
Once the signal is a clean, conditioned voltage, it has to become a digital code, and that conversion is not free either. An analog-to-digital converter maps a continuous voltage onto one of 2^N discrete codes spaced by a quantization step = /2^{N} , and that rounding itself injects noise, with power approximately /12 spread across the sampled bandwidth. The industry-standard way to describe and test this — offset error, gain error, integral and differential nonlinearity, effective number of bits — is defined by IEEE Standard 1241, which exists precisely so that a converter from one vendor can be compared against another using the same measured definitions rather than…
Learn the underlying idea
A subscript is a label attached below a symbol. It often selects a time step, component, category, or member of a sequence.
