Christian Joas describes E-60LD,
the latest architecture for the GSM-
Terminal baseband function which
allows GSM mobile telephone pro-
ducers to develop innovative and
reasonable solutions. E-GOLD will
support "high-speed data" to the
GSM+ standard. Highest speech
quality is achieved without
additional hardware. 16

Inductive components of high-
permeability materials are vital to
digital communications - not only
in today's ISDN, but also in emerg-
ing broadband technologies such
as ADSL. The outstanding magnet-
ic properties and symmetry of
toroidal cores from VACUUM-
SCHMELZE ensure opti-
mum transmission. 18

The overwhelming success of the
TVTEXT series continues with new
features, report Wolfgang Berth in
and Jlirgen Stoiber. Additions to
the component series offer up to
64 colors, larger Code-ROM, as
well as simpler and more flexible
OSD programming via spe-
cial hardware windows. 24

Innovative ferrite polymer corn
posite film from Siemens Mat-
sushita Components not only re-
duces core losses and self-heating
in power transformers and chokes,
but also paves the way to more
compact design and economical
production of inductive corn-
ponents. 32

Resourceful designers at Siemens
Electromechanical Components
have shrunk the volume of the
fourth-generation T4 telecom
relays 60% of that of the previous
generation - without sacrificing
performance or reliability. With full
surface mounting capability, the T4
can be used to implement
32-port line cards. 35
