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.
The following data apply to a 100-kW, 250-V, six-pole, 1000-r/min long-shunt compound generator: no-load rotational losses 4000 W, armature resistance at 75°C = 0.015 , series-fie
Q. Explain Resistance-capacitance coupling? It is the most commonly used coupling in discrete device amplifier as it is least expensive and has satisfactory frequency response.
Explain junction transistors (npn and pnp). Junction Transistor: This transistor consists of two p-n junctions combined in one crystal as demonstrated in figure below.
