Abstract
A system that improves acquisition fidelity in high-bandwidth interleaved acquisition systems through a process called sample-synthesis. Synthesizers are used to make data from one digitizing element appear as though it were sampled by another digitizing element. This method overcomes the Nyquist limitations imposed on a single digitizer. The topology for this system is described, and an explanation of the operation is provided. Then, details are provided for the consideration of Infinite Impulse Response (IIR) and Finite Impulse Response (FIR) filter implementations of sample synthesizers.
