Abstract: A method employing a unique mixture of microwave and digital signal processing is described that provides for large bandwidth increases in waveform digitizers. Such digitizers are a critical component of 100+ Gb/s optical transmission systems. A 30 GHz Bandwidth, 80 GS/s Sample Rate Real-time Waveform Digitizing System Peter J.
