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 […]
What is isotropic orthotropic and anisotropic materials?
What is isotropic orthotropic and anisotropic materials? Orthotropic materials are a subset of anisotropic materials; their properties depend on the direction in which they are measured. An isotropic material, in contrast, has the same properties in every direction. It can be proved that a material having two planes of symmetry must have a third one. […]
How are electric motors and electric generators similar?
How are electric motors and electric generators similar? The motor and the generator are almost similar from the construction point of view, as both have stator and rotor. The main difference between the two is that the Motor is an electric device which converts electrical energy into mechanical energy. The generator is vice versa of […]
Which of the following is the cause of test anxiety?
Which of the following is the cause of test anxiety? Poor study habits, poor past test performance, and an underlying anxiety problem can all contribute to test anxiety. A few potential causes of test anxiety include: Fear of failure: If you connect your sense of self-worth to your test scores, the pressure you put on […]
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 […]
How many phases are found on a binary isomorphous phase diagram?
How many phases are found on a binary isomorphous phase diagram? separation into two phases. What is a phase in a phase diagram? Phase diagram is a graphical representation of the physical states of a substance under different conditions of temperature and pressure. A typical phase diagram has pressure on the y-axis and temperature on […]
