RECAT - Redundant Channel Alignment Technique

Abstract

A problem in the analog-to-digital, (A/D), conversion of broadband tape recorded data occurs when the desired number of simultaneous data channels exceeds the number of available A/D converter channels. A technique for overcoming this difficulty has been developed using two common data channels between multiple passes over the same section of data. RECAT, or Redundant Channel Alignment Technique, is used to align data taken on one pass with data from any other pass. The accuracy of this alignment is a function of the digital sampling rate used, and for highly accurate alignments a sampling rate several times the Nyquist rate is often required.
