Low Frequency Effects. Dolby Digital and DTS 5.1 soundtracks

Stands for Lithium Ion. Many digital cameras take a dedicated
Li-ion rechargeable battery. They hold more power than
other types of battery, and don't suffer from the 'memory
effect', where a partially charged battery, when recharged,
will only register the additional charge rather than its
The Low Noise Block does several things: its horn focuses
the reflected beam from the dish down onto a tiny aerial
inside the LNB. In the modern "voltage switching"
LNB there are two aerials - one for Horizontal and one
for Vertical signals. The signals go right through the
thin plastic rain cap on the horn and are received by
the two aerials inside. These weak signals are amplified
by an electronic amplifier. As these very high microwave
frequencies are used the LNB then converts them into lower
frequencies which will go down coax cable.
Long Wave. A type of radio broadcasting.
