lamplitude

Lamplitude is a term that appears in some technical discussions but does not have a single, universally accepted definition. In contexts where it is used, lamplitude generally refers to a magnitude or amplitude that is linked to a parameter, often denoted by the Greek letter lambda (λ). Because lamplitude is not standardized, its precise meaning and notation can vary between authors and disciplines.

The word is typically treated as a portmanteau of lambda and amplitude, or as a stylized way

Possible interpretations include: a parametric amplitude L(λ) representing the magnitude of a quantity as a function

Example: in a sinusoidal signal x(t; λ) = L(λ) cos(ω t + φ), the factor L(λ) serves as the lamplitude,
