Conclusions A software simulation of a lock-in amplifier has been developed that allows the user to analyse both simulated and real (measured) signals. The software implements a model of a lock-in amplifier and provides a means of investigating the propagation of uncertainties through the model using a Monte Carlo method. , signals having welldefined properties, and real signals, will be undertaken to obtain a better understanding of the effectiveness of lock-in amplifiers in recovering signals (in terms of their amplitude and phase) from noise.
Uncertainty Evaluation Measurement uncertainty is estimated for both methods following the Guide to the expression of uncertainty in measurement (GUM) . The measurement model is presented along with the standard uncertainties components, the 29 sensitivities coefficients, the combined uncertainty and the expanded uncertainty. 1. The Measurement Model and Uncertainty Components For gravimetry and for a reference temperature of 20 ºC, the following model was used : V20 = f (m , ρ A , ρW ρ B ,t ,γ ,Vmen ) = (m2 − m1 ) × ρ 1 (1) × 1 − A × [1 − γ (t − 20)] + δVmen ρ W − ρ A ρ B The standard uncertainties are due to the mass measurement (m2-m1), water density (ρW), mass pieces density (ρB), air density (ρA), cubic thermal expansion coefficient of the material of the standard volume measure (γ), water temperature (t) and the meniscus reading.
