Let D n = { 0 , a n , b n } = { 0 , 1 , 2 } ( m o d 3 ) , p n ∈ 3 Z + , n ≥ 1 , satisfy sup n ≥ 1 max { | a n | , | b n | } p n < ∞ . It is well-known that there exists a unique Borel probability measure μ { p n } , { D n } generated by the following infinite convolution product μ { p n } , { D n } = δ p 1 − 1 D 1 ⁎ δ ( p 1 p 2 ) − 1 D 2 ⁎ ⋯ in the weak convergence. In this paper, we give some conditions to ensure that there exists a discrete set Λ such that the exponential function system { e 2 π i λ x } λ ∈ Λ forms an orthonormal basis for L 2 ( μ { p n } , { D n } ) .
