Voltage to Current Converter Circuit: Occasionally in industrial electronics, it is necessary to provide a current proportional to certain voltage, even though the load impedance may vary. A circuit which can perform this job, is…
Summing, Scaling and Averaging Amplifier: The most useful of the op-amp circuits employed in analog computers is the summing amplifier circuit. This circuit can be used to add ac or dc signals. This circuit provides…
Frequency Response of Common Mode Gain of Differential Amplifier: Low values of common-mode gain are desirable so that the circuit can reject undesirable signals that are applied equally to both inputs. The common-mode (CM) gain…
Compensating Network in Op Amp: In op-amps the variations in gain and phase shift with respect to frequency are due to the internal capacitors and stray capacitances, which are due to physical characteristics of semiconductor…
Single Stage Amplifier Frequency Response and Phase Response Curves: The voltage gain of a single-stage transistor amplifier commences to fall off at some high frequency. This fall-off may be due to the construction of the…
Nuclear Waste Disposal and Safety: Introduction - Nuclear Waste Disposal and Safety from nuclear power plants activities, defense related nuclear weapon activities or other applications of nuclear technology is hazardous to many life forms and the…
Automatic Combustion Control System: Automatic Combustion Control System is very popular nowadays and this has been developed mainly to maintain load against demand, to prevent smoke, to increase boiler house efficiencies, to carry out routine…
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…
MHD Power Plant Working Principle: MHD Power Plant or Magneto Hydro Dynamic is concerned with the flow of a conducting fluid in the presence of magnetic and electric field. The fluid may be gas at…
