The properties of two recursive estimators of the Fourier coefficients of a regression function fL2[a,b] with respect to a complete orthonormal system of bounded functions (ek) , k=1,2,..., are considered in the case of the observation model yi=f(xi)+ηi, i=1,...,n , where ηi are independent random variables with zero mean and finite variance, xi[a,b]R1, i=1,...,n, form a random sample from a distribution with density ϱ =1/(b-a) (uniform distribution) and are independent of the errors ηi, i=1,...,n . Unbiasedness and mean-square consistency of the examined estimators are proved and their mean-square errors are compared.
