A short- dipole antenna is placed at the origin while anothershort-dipole antenna is located at a point given in sphericalcoordinates as P (1000,π/4,π/4). Both Antennas arealigned parallel with the Z-axis . Assume that the efficiency ofthe antennas is er=0.9. If we drive the one of theantennas with 1 KW of power at 1 GHZ, what will be the powerrecieve at the terminal of the other antenna ?
A micrometer caliper is used to measure the diameter of a bolt and a reading of 0.768 inches is obtained. Based on this measurement, find the smallest possible diameter and the largest possible diameter.
The transfer function of a causal LTI system is H(s)= 1/(s^2+4) Suppose we would like the output y (t) to be identical to zero for t = 0. If we let x (t) =δ(t), what would the initial conditions be equal to
Discuss the differences between series and parallel circuits. What are some advantages and disadvantages of each type Discuss why the total power equals the sum of the individual values of power, whether a series circuit or a parallel circuit is us..
