Basic Principles of Data Transmission Technology 1. Characteristic Impedance and Delay Characteristics Ideally, due to the in-phase relationship between the voltage and current of the resistive components, the input signal experiences no phase shift when passing through the resistive network, only inherent attenuation. In practical circuits, since cables do not possess purely resistive characteristics but … Read more
