1. An apparatus comprising:

  • a sampling circuit which performs lossy sampling of a continuous signal to provide a corresponding sequence of discrete samples at a sampling rate less than a Nyquist rate of the continuous signal;

    a processing circuit which reconstructs an informational content of the continuous signal from the discrete samples, the processing circuit configured to insert at least one additional sample into said sequence to increase an effective rate of said sampling; and

    a memory space coupled between the sampling circuit and the processing circuit which temporarily stores the sequence of discrete samples.
