  The SND is a non-magnetic detector deployed at the VEPP-2000 $e^+e^-$
collider (BINP, Novosibirsk) for hadronic cross-section measurements in the
center of mass energy region below 2 GeV. The important part of the detector is
a three-layer hodoscopic electromagnetic calorimeter (EMC) based on NaI(Tl)
counters. Until the recent EMC spectrometric channel upgrade, only the energy
deposition measurement in counters was possible. A new EMC signal shaping and
digitizing electronics based on FADC allows us to obtain also the event time
structure. The new electronics and supporting software, including digital
signal processing algorithms, are used for data taking in the ongoing
experiment. We discuss the amplitude and time extraction algorithms, the new
system performance on experimental events and physical analysis applications.
