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 ?
Your new assistant has measured the signal coming from a piece of test equipment, writing v(t) = Vxe(-2+j60)t, where Vx = 8-100V. (a) There is a missing term, what is it and how can you tell it's missing (b) What is the complex frequency of the si..
Design a NMOS resistive load inverter for: VDD = 5V P = 0.2 mW when Vlow = 0.1V kn = 60 micro Ampere / V^2 VTN = 0.25V Find the load resistor and the W/L ratio for the switching transistor.
What is the system reliability for a light panel containing 12 light bulbs, and only requires 9 bulbs to be working for success (only 3 failures allowed). The reliability performance of the bulbs is based on the exponential reliability distributio..

An RL circuit takes a current of 7A that lags behind the 231-volt source by 35 electrical degrees. Calculate the power factor, impedance, resistance and inductance of the circuit.
Discuss the advantages of transforming time-domain circuits into the corresponding frequency domain. How does this change the way circuits are analyzed
If the attenuation coefficient for the wave in equation E =Eoe-αzsin(ωt - kz) has the value 2x 10-5 cm-1, compute the power loss in dB for1 km. Compute the fractional loss for 1 km.
An incident -ray photon is scattered from a free electron that is initially at rest. The photon is scattered straight back at an angle of 180 degrees from its initial direction. The wavelength of the scattered photon is 9.00×10^-2 nm.
One step in decoding a simple code without knowing the coding scheme , involves counting the number of occurrences of each character. Then, knowing that the most common letter in English is "e" the letter that occurs most commonly
