A perfect conductor with bias voltage Vo is insulated with a wedge shaped dielectric material of angle, =450, whose relative permittivity is εr. Use electrostatic boundary conditions to determine the electric displacement, D, and electric field intensity, E, in conductor, the dielectric and the air (εair=1) above the material. Determine the angle at which the electric field exits the dielectric and enters the air. Full credit will only be given to those that start from Maxwell's equations and derive the conditions required to satisfy the problem at each step.
The continuous-time counterpart to the N-point discrete-time MA filter is the I-interval continuous-time MA filter given by the input/output relationship y(t)=(1/I)*Integral of x(lamda) delta lambda where the bounds are from t-I
Compare the field at the center of a Helmholtz coil pair and at the center of a solenoid, if both use the same total length of wire and carry the same current.Take the solenoid length equal to the spacing between the Helmholtz coils
Using the LM555 data sheet, make an estimate of the maximum fundamental operating frequency in the astable mode.
Determine the signal/noise ratio (Eb/No) in input of the receiver for each modulation format presented below if symbol error rate (SER) is required to be 10-^4 (use the coherent detection), for the solution the appropriate graphs can be used inste..
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.
Two random variables X and Y have a joint probability density function given by f(x,y) =kxy 0
A 10kVA, 200/400V 50Hz single-phase transformer gave the following test results. O/C test: 200V, 1.3A, 120W, on l.v. side. S/C test: 22V, 30A, 200W on h.v. side. (a) Calculate the magnetizing current and the component corresponding to core loss at ..

Design a BCD-to-7-segment decoder/driver (code converter) by using two different VHDLs (two projects - one low elvel and one high level) You need to turn in vhdl codes, testbench codes, simulation waveforms
two metal sheets form a wedge shaped space. In cyllindrical coordinates, sheet 1 is described by (phi=0,p>0) and sheet 2 is described by (phi=30deg, p>0). A small gap at the z axis prevents the sheets from contacting
