The input to a certain filter is given by Vin(t)=2cos(10000pi*t-15deg) and the steady state output is given by Vout(t)=5cos(10000pi*t+25deg).Determine the (complex) value of the transfer function of the filter for f=5000 Hz. Express answer in polar notation expressing argument in degrees. H(5000)=?
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.
In the United States, coal is a fossil fuel, used mainly to fuel the energy needed for electric power plants to manufacture electricity. The air pollution caused by burning coal has been linked to health problems and concerns for the general popul..
