Given two NPN BJTs having β= 100 and ro = 100 Kohm. Using a single 5V dc power supply, design a differential pair amplifier having 1mA bias current in each transistor. What is its maximum gain for linear operation (balanced input, unbalanced output)?
A plane wave in air with an electric field amplitude of 20 V/m is incident normally upon the surface of a lossless, nonmagnetic medium with Xr er = 25. Determine the following: a.) reflection and transmission coefficient
A farmer owns two barns; one north of a creek and the other south of the creek. The farmer has a Cabbage, a Goat, and a Wolf. The Farmer needs to put each item in a barn every night. If the Cabbage and Goat are in the same barn
A three-phase 45 MVA, 345/34.5 kV distribution transformer is used as a step-down transformer. Determine the phase VA, Voltage, Current ratings and turns ratios of the transformer if it is connected as follows (a) Wye -delta

Construct a table showing the current for values of time between 0 and 9 hours at intervals of 1 hour.Hence draw a graph of i against t for 0 is smaller or equal to t is smaller or equal 9.(cannot type in proper inequality symbols)
Find the amount of work required for rearranging a uniformly distributed surface charge Q of radius a into a uniformly distributed volume charge of radius a how can i do this problem in 2 different ways.
In a vessel with a volume 3 m3 you put 0.03 m3 of liquid water and 2.97 m3 of water vapor so that the pressure is 101.33 kPa. Then you heat the system until all liquid water just evaporates. What is the pressure and temperature in the vessel at th..
Given the following: i) The column vectors: X1=[2 4 6]'; X2=[4 5 7]'; X3=[7 8 3]' % Note the above are column vectors (% In Matlab, ' means Transpose). ii) The matrix: A=[X1 X2 X3]. 1)B=A'; % In Matlab, ' means Transpose. This defines B.
A storage tank has a Diameter of 20ft and a height of 10ft. The output volumetric flow from this tank is given by fout(t)=2h(t) where h(t) is the height of the liquid in the tank. At a particular time the tank is at steady state with an input flow..
Develop the ow-graph for the FFT algorithm from the radix-2 FFT algorithm for the N = 9 case in which the input is in the bit-reversed order and the output is in normal order.
