An internally compensated op amp is specified to have an open-loop gain of 106dB and a unity-gain bandwidth of 3MHz. Find fb and the open-loop gain in dB at fb.
write an 8051 program that would generate a 200khz, 50% duty cycle, square wave at P1.0.Use Timer 0 for the delay. Ignore the overheads cycles due to the instructions in the loop. Assume 12 MHz clock. All data must be hex.
A line has an inductance of1.25mH/km with an impedance angle of 70 degree , and a capacitance to neutral of 0.01mF/km. Calculate its reactance and series impedance per unit length at 50Hz. Calculate the line admittance per unit length
what is the shortest possible line length that would exhibit the desired reactance at its input?
If the concentration of free electrons is 10^29 electrons per cubic meter and if they are uniformly dispersed throught the wire, then what is the average velocity of an electron ?
Draw the equivalent circuit referred to the high-voltage side.
Problem Feeder - Transformer, A single-phase load is supplied through a 35 kV feeder whose impedance is 115 + j380 Ohms and a 35 kV, 2400 V transformer whose equivalent impedance is 0.26 + j1.21 Ohms referred to its low voltage side.
What is the resistivity of the wire? conductivity? Using the original dimensions of the wire, how much current can you pass through the wire until a 5V signal is degraded 5% or more?
Energy of a moving charge, A region in space has an Electric field given by E = x(x^) - y(y^) + xy(z^) where (x^), (y^), (z^) indicate corresponding letter with caret on top of it.
An npn BJT has an emitter area of 2micrometer^2. The doping concentration in the base is Nb=3x10^16/cm^3. The BJT is operating with Vt=26mV and ni=1.5x10^10/cm^3. For electrons diffusing thru the base Dn=34cm^2/s.
A circular loop TV antenna with 0.01 m2 area is in the presence of a uniform -amplitude 300 MHz signal. When oriented for maximum response, the loop develops an emf with a peak value of 20 mV. What is the peak magnitude of B of the incident wave?
Which one of the following statements is correct?
