Consider two alternatives for designing an amplifier having a dc gain of 100. The first alternative is to use a single non-inverting stage, having a gain of 100.The second alternative is to cascade two non-inverting stages, each having a gain of 10. Op amps having a gain bandwidth product of 106 are to be used. Write an expression for the gain as a function of frequency for each alternative. Find the 3-dB bandwidth for each alternative.
The electron and hole concentrations as a function of energy in the conduction band and valence band peak at a particular energy. Consider silicon and assume Ec - EF =0.20 eV. Determine the energy, relatiive to the band edges
A three-phase Y- connected transformer bank (single phase) consists of three identical step-up transformers rated at 100MVA, 13.8kV:66.4kV. Each transformer has a series impedance of .0045 + j0.19-ohm referred to its 13.8kV winding.
A cast-iron cylinder of 300mm bore carries a pressure of 30 Newtons per square millimetre; what should be its thickness for a unit working stress of 25 newtons per square millimetre?
There is some interest from industry to be able to track the solidification or drying of the paint layer as it happens to ensure correct thickness and material properties. One way to do this would be to measure the changing values of the permittiv..
In case Ampere meter is connected in series with load. if there is also a short path, then what will be the current in Amp-Meter?
Calculate: Critical frequency for the input low pass network, and the output low pass network, estimate the values for Cbe, Cjc, Cbc, and Cje. Concider the resistance of the signal sourceRs to be equal to the 1 ohm resister in series with the source.
Phase current - Neutral Grounded Assume that the load is star connected with the neutral grounded. Each phase has a series RL load with R = 5 ohms and L = 20 mH. Calculate and plot the Phase a current Ia using Fourier techniques.
Write a C program to toggle PB3 of PORTB ON and OFF, with a 0.5-ms delay after each toggle. Assume that clock frequency is 6.25 MHz. Write inline assembly-language code inside of the delay function.
A temperature transducer has the relationship R=200 + 10T where R is in ohms and T is in Celsius. The problem specifications are: Range is 30=T=50°C Resolution is 0.01°C Frequencies of interest are 0 to 100Hz Transducer dissipation constant is 20 mW..
a 9.1 v zener diode exhibits its nominal voltage at a test current of 28 mA . at this current the incremental resistance is specified as 5 ohms . find Vz0 of the zener model . find the zener voltage at a current of 10 mA and at 100 mA.
A 10-hp six-pole 60-Hz three-phase induction motor runs at 1160 rpm under full-load conditions. Determine the slip and the frequency of the rotor currents at full load. Also estimate the speed if the load torque drops in half.
The internet connection speed at any time from your home can depend on the amount of overall internet trac at that time. Let the random variable X denote the speed of connection in megabits per second (MBPS).
