Effect of Negative Feedback on Output Impedance: Just as high input impedance is advantageous to an amplifier, so is low output impedance. With lower output impedance, the amplifier is better suited to drive a low…
Effect of Negative Feedback on Input Impedance: High input impedance is always desirable in an amplifier as it will not load the preceding stage or the input voltage source. Such a desirable characteristic can be…
Effect of Negative Feedback on Bandwidth: The effect of negative feedback on bandwidth is given below as From Eq. (19.8) voltage gain with feedback is given as and from the above result it may be…
Effect of Internal Transistor Capacitance: As we know already that at high frequencies, the coupling and bypass capacitors act as short circuit due to their low reactance and hence the voltage gain is not affected.…
Effect of Earth on Capacitance of Transmission Line: In calculating the Effect of Earth on Capacitance of Transmission Line, the presence of earth was ignored, so far. The effect of earth on Capacitance of Transmission…
EEPROM (Electrically Erasable Programmable Read Only Memory): Electrically Erasable Programmable Read Only Memory (EEPROM) also use MOS circuitry very similar to that of EPROM. Data is stored as charge or no charge on an insulated…
Eddy Current Drives: Eddy Current Drives consists of an eddy current clutch placed between an induction motor running at a fixed speed and the variable speed load. Speed is controlled by controlling dc excitation to…
Economics in Plant Selection: Economics in Plant Selection - The plant capacity and size depends upon the power demand. A power plant should be reliable i.e. its capacity must be more than the predicted maximum…
Economic Operation of Power Plants Interview Questions and Answers: 1. Is the cost of fuel directly proportional to power output ? Ans. No, the cost of fuel does not vary directly in proportion to the…
Economic Choice of Transmission Voltages: It has been shown earlier here that if transmission voltage is increased, the volume of conÂductor material required is reduced. This decreases the expenditure on the conductor material. It may…
