Question:
A uniform plane wave propagating in a medium has
E→ = 2e-azsin(108t -βz)ayV/m
If the medium is characterized by εr = 1, μr = 20, and σ = 3S/m, find α, β, and H→.
A first-order allpass filter impulse response is given by h(t) = - d(t) + 2e^(-t)*u(t) a) find the zero-state response of this filter for the input e^(t)*u(-t). b) sketch the input and the corresponding zero-state response.
Since typical operating magnetic flux densities exceed the saturation flux densities of iron, these machines are typically designed withoutiron in the magnetic circuit; as a result, these machines exhibitno saturation effects and have low synchron..
Two infinite sheets of charge lie parallel to each other, separatedby a distance d. The upper and lower sheets have surfacecharge densities ρsa andρsb[C/m2], respectively. find the voltage Vab from the top to the bottom surface.
Design a filter with lower frequency cut-off: 10Hz, upper frequency cut-off: 2KHz, gain of 5, and an input resistance greater than 5kOhms.
