Let h(z) be an essentially bounded complex valued function on the unit circle Y = {z I Iz] = 1}. Consider the corresponding Laurent operator Lt, = (h= m),.meZ, where h= is the nth Fourier coefficient of h(z), h,, = fT h(z)z " dz. Let us consider an operator Sh(p,q), which we shall call a sampling op
