What is path loss in RF?

What is path loss in RF? Path loss, or path attenuation, is the reduction in power density (attenuation) of an electromagnetic wave as it propagates through space. This term is commonly used in wireless communications and signal propagation. How is path loss measured? The path loss is measured by the method of directly measuring the […]

What is a voltage divider circuit?

What is a voltage divider circuit? In electronics, a voltage divider (also known as a potential divider) is a passive linear circuit that produces an output voltage (Vout) that is a fraction of its input voltage (Vin). Voltage division is the result of distributing the input voltage among the components of the divider. What is […]

What is a system in Systems Engineering?

What is a system in Systems Engineering? At NASA, “systems engineering” is defined as a methodical, multi-disciplinary approach for the design, realization, technical management, operations, and retirement of a system. A “system” is the combination of elements that function together to produce the capability required to meet a need. What are systems engineering principles? Principle […]

What is substitution cipher in cryptography?

What is substitution cipher in cryptography? Substitution ciphers encrypt the plaintext by swapping each letter or symbol in the plaintext by a different symbol as directed by the key. Spaces in the ciphertext are just added for readability; they would be removed in a real application of the cipher to make attacking the ciphertext more […]

What does the Fisher equation tell us?

What does the Fisher equation tell us? The Fisher equation is a concept in economics that describes the relationship between nominal and real interest rates under the effect of inflation. The equation reveals that monetary policy moves inflation and the nominal interest rate together in the same direction. What affects nominal interest rate? Key Terms […]

Can thrust angle be adjusted?

Can thrust angle be adjusted? Most thrust angle problems on these suspensions can be resolved with toe adjustments. But, if the cradle has shifted, you may quickly run out of adjustment on the toe links. How do you correct thrust angles? The thrust angle is the angle between where the rear are directed and the […]
