Each effective capacitance has associated with it an effective noise
current (#tex2html_wrap_inline1312#) in parallel with a power of #tex2html_wrap_inline1314#. Each of
these noise currents is zero centered and has a root mean square
amplitude dependent on the actual capacitance. Equation
#eqnmatrix#265> is then solved for each of the noise sources
independently. Each of the noise currents across the pair of receiver
electrodes is then RMS summed:
#equation266#
This final noise current can then be used with the receiver impedance
to get an mean square voltage amplitude.
The resultant thermal noise is confirmed to be as expected, very
small. A typical value for this mean square voltage is #tex2html_wrap_inline1316#.
