Symbols of the Federal Bureau of Investigation on domestic intelligence matters with the invention of the motto: "He's credited in some bureau histories with inventing (in 1935) not only the bureau's name, but its official motto: Fidelity, Bravery, Integrity." The outer edge of the seal consists of a series of beveled golden peaks. This represents the severe challenges that the FBI faces every day and alludes to the ruggedness of the organization. The gold color represents the richness and history of the Bureau's mission. The FBI seal should not be confused with the FBI badge, which dates from 1935 and has a very different design that does
Signal integrity Signal integrity 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 (or current) 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 effects can degrade the electrical signal to the point where errors occur and the system
