ansient Model Transient Model om the previous lecture we determined that From the previous lecture we determined that any function with the argument (t z/u) or z ) would be a solution to the wave (t+z/u) would be a solution to the wave equation. e voltage function: The voltage function: ܸ ൌ݂ ቀݐെ ݖ ݑ Represents a voltage signal travelling in the +z direction McGill ECSE 352 Fall 2011 D. Davis 2
ansient Model Transient Model e current related to this voltage can be The current related to this voltage can be found using the telegrapher equations: ߲ݒሺݖ, ݐሻ ߲݅ሺݖ, ݐሻ Since the partial derivative with respect to z ߲ݖ ൌെܮ ߲ݐ will produce: And: 1 ݑ ߲݂ ሺݓሻ ߲ݓ ߲݂ ሺݓሻ ߲ݓ McGill ECSE 352 Fall 2011 D.
