Time-domain Reflectometry or TDR is a measurement technique used to determine

the characteristics of electrical lines by observing reflected waveforms.The amplitude of the reflected signal can be determined from the

impedance of the discontinuity. The distance to the reflecting impedance can also be determined from

time that a pulse takes to return..

Electrical impedance, or simply impedance, is a measure of opposition to a sinusoidal alternating electric current
