Introduction
Introduction
A zoom spectrometer is an spectrometer that use the techniques of down-sample and decimation, to reduce its frequency rate, and at the same time increase its frequency resolution. In this project a zoom spectrometer is implemented in ROACH2 for multiple zooming frequency windows working in parallel.
