Abstract
A harmonic time interleave (HTI) system can include a sample clock to provide a reference signal, a summing component to receive the reference signal and a second input, a splitter component to receive an input signal, and delay blocks to each receive an output from the splitter. The HTI system can also include digitizing components to receive the reference signal from the sample clock and an output from each of the mixing components, and a poly-phase filter matrix block to receive an output from each of the digitizing components. The HTI system can also include an interleave reconstruction block to receive an output from the poly-phase filter matrix block and interleave time domain signal samples from each digitizer to create a reconstructed waveform.
