Signal integrity or si is a set of measures of the quality of an electrical signal. In digital electronics, a stream of binary values is represented by a voltage waveform. However, digital signals are fundamentally analog in nature, and all signals are subject to effects such as noise, distortion, and loss. Over short distances and at low bit rates, a simple conductor can transmit this with sufficient fidelity. At high bit rates and over longer distances or through various mediums, various effec.

Quality refers to whether the signal is within the voltage (threshold) levels that can be recognized by the receiver. When a digital signal travels from the transmitting end to the receiving end, these parameters can degrade due to properties of the transmission media.
