Title:
HIGH BANDWIDTH REAL TIME OSCILLOSCOPE
Document Type and Number:
WIPO Patent Application WO2004038432
Kind Code:
A3
Abstract:
A method and apparatus for digitizing a data signal, the method comprising the steps of receiving an input analog data signal (100), splitting (112) the received input analog data signal into a plurality of split signals, and mixing (116) at least one of the split signals with a predetermined periodic function with a predetermined frequency. The split signals are then digitized (106, 111) and combined (132) mathematically to form a single output data stream (135) that is a substantially correct representation of the original input signal.
