TRestRawCommonNoiseReductionProcess Class Reference

Detailed Description

A process to subtract the common channels noise from RawSignal type.

BASIC DOCUMENTATION : Full documentation to be added. A figure with the the pulses before and after applying the process.

This process tries to reduce the common noise of TRestRawSignals by two means :

Common noise identification in all signals or by blocks Written with TREX-DM architecture in mind (8 blocks with 68 signals each and gap of 4 ID between blocks)

Output signal without base line subtraction.
