The entry of noise into the intrabody signalling system comes from
three sources:
- <#92#>Interference.<#92#> Environmental noise, both background, other
unintentionally interfering devices, and other intrabody signalling devices
all produce a highly variable amount of noise.
- <#93#>Thermal, in body<#93#> noise, as contributed by the actual transmission of
the data through the body. Each equivalent capacitor contributes
#tex2html_wrap_inline1288# noise power.
- <#96#>Amplification<#96#> noise. Whatever amplification system is used in the
receiver affects the total noise in the channel.
Amplification noise is expected to dominate, though clearly external
interference has potential to be significant, depending substantially
on the encoding scheme selected.
