Explain Noise
Noise is unwanted signals which degrade the desired signal content and therefore the performance of the system. Noise might be produced either externally or internally to the system. External noise contains atmospheric interference, man-made interference, lightning, etc. Internal noises are produced by the components and devices used in the system.
Partial derivatives - Transistor hybrid model: The partial derivatives are taken by keeping the collector voltage or base current constant as pointed out by the subscript atta
Q. If a single phase motor fails to run or start slow what action to be taken. Ans: If it is not starting check the supply and test the winding if it found normal check
Q. What is the function of CT and P.T and where they are used? Ans: The full form of CT is Current transformer and is used for calculating of current. The full form of PT is
Q. Three single-phase 100-kVA, 2400:240-V, 60-Hz transformers (each ofwhich has an equivalent series impedance of 0.045+j0.16 referred to its low-voltage side) are connected to fo
What is the size of ports in 8255? Port-A : 8-bits Port-CU : 4-bits Port-B : 8-bits Port-CL : 4-bits
Q. Explain a common emitter configuration without a feedback. A simple common emitter transistor amplifier--having no negative feedback--is not an ideal amplifier. This is beca
Q. Consider an amplifier as a voltage source with an internal resistance of 72 . Find the turns ratio of the ideal transformer such that maximum power is delivered when the amplif
Capacitors : These are electrical condensers having a system of electrical conductors and insulators. The simplest form consists of two parallel metal plates separated by a layer
