servos
SBEC
- Switching Battery Eliminator Circuit, is a 5V-6V regulator switch mode type handles more input
voltage and have lower loss
RC Receiver Battery or Supply
, is normally 4 or 5 NIMH cells providing 4.8 or 6V of steady and stable
supply, such a battery must be able to handle
all servo max currents and still provide sufficient stable voltage, do not use spring loaded battery cassettes
or weak current capable cells like normal alkaline types,
Today more new and fancy battery types like lipo and lion and such can also be used if receiver
and servos can handle the different voltage range they provide.
Fading
- when the distance and positions and angles of a wireless system is changed the radio signal will
also change
Multipath Fading
- A direct signal and a reflected signal hit receiver antenna with -180 deg phase, creating
a zero signal level
Nulling
- is the same as Multipath fading
FHSS
- Frequency Hopping Spread Spectrum, a way to send data using many different frequencies, makes a
system immune to noise and jamming proof.
