Calculation of Signal Strength

To solve this network, the following system of equations are solved simultaneously. #tex2html_wrap_inline1302# is the impedance between the pair of nodes a and b.

#equation176#

#equation182#

Here, I is an arbitrary transmitter current. Node 6 is set arbitrarily to 0, and the other nodes will be relative to it.

The signal strength will be proportional to the square of the voltage difference between the receiving electrodes. The actual value calculated will be arbitrary, as the currents in the transmitter were chosen arbitrarily in Equation #eqnmatrix#234>. Values for the voltage difference at the transmitter will have also been calculated, and due to the system being a linear network, the output voltage for any arbitrary input voltage can be calculated.
