Characteristics of Wireline Transmission Impedance: expressed in Ohms, is the combined effect of a circuit’s inductance and capacitance. Propagation Delay and Latency: the difference in time between a data packet’s transmission and its reception over a specific route. Distortion: the unintended and undesirable modification of at least one signal component, which makes the signal different from how it was originally transmitted. Noise: any unwanted interference from external sources.
