  The large growth of flash ADC techniques for processing signals, especially
in applications of streaming data, raises issues such as data flow through an
acquisition system, long-term storage, and greater complexity in data analysis.
In addition, experiments that push the limits of sensitivity need to
distinguish legitimate signals from noise. The use of correlation coefficients
is examined to address these issues. They are found to be quite successful well
into the noise region. The methods can also be extended to Field Programmable
Gate Array modules for compressing the data flow and greatly enhancing the
event rate capabilities.
