An analog signal has a bandwidth of 80 kHz and must be digitized in an ADC. The peak voltage is 6V and you need to maintain a resolution of 0.034V. Find the number of bits per sample and then calculate the total number of kbps needed in the ADC. Remember that you cannot have a fraction of a bit in a sample.
An abrupt p-n junction has a doping concentration of 1015, 1016, or 1017 cm-3 on the lightly doped n-side and of 1019 cm-3 on the heavily doped p-side. Obtain series of curves of 1/C2 versus V, where V ranges from -4 to 0V in steps of 0.5V.
A limited source diffusion is used to define the base of an npn transistor. Estimate the starting concentration of impurity if the base-collector junction lies 1micro-meter below the surface after 2h diffusion at 1100 degrees C.
A pipe of inner radius 4 cm, outer radius 6 cm, and infinate length is centered on the z-axis. Charge is evenly distributed within the wall of the pipe in the amount of 16 coulombs per meter length.Find and Plot the electric feild density as a fun..

The location of the zeroes in the spectrum suddenly changes to 5 kHz, 10 kHz, 15 kHz.... What parameter of the rectangular pulses has changed and what is its new value?
At a point f in the system, there is an open-circuit fault on phase-a with a voltage across the open-circuit as Vfa , whereas Vfb =Vfc =0. Similar to the calculations of the short-circuit currents by making use of the sequence networks
A 15 hp, 209V,three-phase,six pole, Y-connected induction motor has the following parameter values per phase: R1= 0.128 ohm, R'2=0.0935 ohm Xeq- X1 + X'2 = 0.49 ohm. The motor slip at full load is 3%, and the efficiency id 90%.
