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.
Q. Draw the complete circuit of a dual voltage source using 7805 and 7905. A voltage regulator is a circuit that supplies a constant voltage regardless of changes in load curre
Define Lines Parameters In power system analysis, the parameters of interest when modelling power lines are: inductance, capacitance, series resistance and leakage resistance.
Q. Referring to Figure, let V BN = V RN = 120 V rms magnitude, and V BR = 240 V rms magnitude. Write down expressions for v BN (t), v RN (t), and v BR (t), and sketch them as a
Q. If b and a are the radii of the outer and inner conductors, respectively, of a coaxial cable using a polyethylene dielectric (ε r = 2.26), what ratio b/a is needed for the cabl
Q. Show Block diagram of proportional and integral controller? The block diagram of Figure illustrates a typical microprocessor system used to implement the digital PI controll
Binary Number Systems As mentioned earlier this number is used by digital systems like microprocessor and other digital circuits. This number systems use only two
De multiplexing Address Data Bus (AD 7 - AD 0 ) As it is already discussed that lower order address bus (A 7 - A 0 ) is multiplexed with data bus (D 7 - D 0 ). Hence pins
what is clamper circuit
Q. Given the K map of a logic function as shown in Figure, in which ds denote don't-care conditions, obtain the SOP expression.
Explain the Voltage Regulation? The percent of voltage regulation of a generator is defined as the ratio of the change in voltage from no-load to full-load to the full-load vol
