| - | | | | | | | | | | | | | | | | | | | + | Every time value encoded in the MTDC is sent by the Filter as a series of two 16-bit words: the first one provides information about the MTDC channel and the hit number; the second one gives the time value for that channel-hit. In the current version (Oct. 2015), the Filter processes up to 32 hits per channel. This value can be increased if necessary. |
