Patent ID: 7212934

Claim:
A method of determining individual string resistance in a network of resistive strings, each resistive string having a unique preselected impedance connected thereto, comprising the steps of: applying a frequency-varying input signal to said network such that portions of said frequency-varying input signal propagate through each resistive string of said network; recording an output signal from said network, said output signal resulting from said portions of said frequency-varying input signal propagating through said resistive strings of said network; and determining a resistance for each resistive string in said network based on said frequency-varying input signal, said unique preselected impedance of each resistive string, and said output signal, wherein said step of determining comprises relating said frequency-varying input signal, said unique preselected impedance for each resistive string, said resistance for each resistive string, and said output signal to each other in one or more mathematical equations and curve-fitting said one or more mathematical equations to a plot of said output signal.
