    "abstract": "The inversion of an FIR data sampling is usually stated to be possible with\nthe use of a potentially unstable IIR, and in particular circumstances. It is\npossible to accomplish the same inversion with the doubling of an FIR sampling\nand with only FIRs for the sampling and the inversion. This note presents the\nconfiguration, which appently is not in the literature, for perfect signal\nreconstruction.",
