Method and apparatus for ensemble averaging repetitive signals

摘要: A spectrometer or similar device is scanned repetitively to produce a series of repetitive output signals either analog digital form. Each signal includes an ensemble timedisplaced components and identical the other except for noise. The averaged (time averaged) by ensambled-averaging computer which scans each samples at plurality sampling points same relative position in ensemble. Digital data point accumulated separate channel memory improve signal-to-noise ratio. An extra bit added into sampled point, such being less than least significant be stored memory. accumulation bits over scans, adds zero some number whereby digitization error reduced.
