In physics, the slowly varying envelope approximation (SVEA, sometimes also called slowly varying amplitude approximation or SVAA) is the assumption that the envelope of a forward-travelling wave pulse varies slowly in time and space compared to a period or wavelength.
 This requires the spectrum of the signal to be narrow-banded—hence it also referred to as the narrow-band approximation.
