A bandlimited signal sampled at a sampling rate higher than the Nyquist rate can be reconstructed uniquely from its samples even when a finite number of samples is being lost. This paper gives a solution to this problem which partially originates from M arks [1]. The solution described here is available in a parallel and a sequential (iterative) form. The parallel implementation requires the solution of a single system of linear equations. Some investigation of the numerical properties of this system is done and a numerical example is given.
