Abstract
The standard calculation of the spectrum of density perturbations prod uced during inflation assumes that there is only one real dynamical de gree of freedom during inflation. However, there is no reason to belie ve that this is actually the case. In this paper we derive general ana lytic formulae for the spectrum and spectral index of the density pert urbations produced during inflation.
