Suppose you go to a consultation meeting with a potential client.The client requires a single beam antenna with HPBW's of theta1 = 15 degrees in one plane and theta2 = 30 degrees in the other plane. During the meeting, the potential client mentioned that they are thinking toremove all amplifiers (about 40dB gain) in the system in order to save cost and improve systemefficiency. Your boss, who is not the antenna expert, replies, "That's ok! We can just compensatefor this by increasing the antenna gain. We can just increase the antenna gain to 50 dB." As theantenna expert, do you speak up? What do you say? Does a gain of 50 dB make sense with theclient's requirements? Note: Use the relationship between gain and HPBW.
Express the diode current equation. A) Define all the diode parameters and draw the I-V characteristics. (Assume non-ideal diode) B) If IF=10 mA, Is=10-15A, VT=25mV, Calculate the voltage drop across the diode.
Consider a square house 40 ft on a side, 10 ft high, with a flat roof on top and walls/roof that is 8 inches thick. The thermal conductivity for an un-insulated wall or roof is 1.6 W/Km, while with fiberglass insulation its 0.04 W/Km.
Four voice signals. each limited to 4 kHz and sampled at Nyquist rate are converted into binary PCM signal using 256 quantization levels. what will be The bit transmission rate for the time-division multiplexed signal.
If 10.6 V is measured across a 5.9 kW resistor and the resistor is in series with a 6.3kW resistor, what would be the current flowing through the 6.3 kW resistor inmA
An electroencephalographic (EEG) signal x(t) is recorded from the surface of the head (scalp) via an EEG recording machine. The EEG machine has a bank of 4 ideal band-pass (BP) analog filters, H1(jω), H2(jω), H3(jω) and H4(jω)
Calculate in polar form the sequence components of unbalanced lineto-neutral voltages and calculate in polar form the phase currents corresponding to the sequence components
A 22KVA, 2300/230 VAC, 60HZ transformer is tested with a short circuit test. The measured data are as follows: Psc=280W, Vsc=80VAC and Isc=9.5 A 1. Find the transformer turns ratio of the transformer
A 1.0000 V signal is converted to an 8-bit binary signal throughand ADC. The signal is then fed back into an 8-bit DAC. assummingthat both ADC and DAC range from 0 to 5.0 V, what would the outputvoltage of the DAC be
why do you have to compute the equivalent resistance of the 6 ohm and 20 ohm. doesnt the current splitfrom the 6 ohm to the 30 ohm and then from the 30 ohm to the 20ohm.
A 6 pole round rotor 3 phase star connected synchronous machine has the following test results: Open circuit test: 4000 V line to line at 1000 rev/min, 50 A rotor current Short circuit test: 300 A at 500 rev/min, 50 A rotor current
Consider the analog filter H(s)=30000/(s^2+400s+30000) , notice that the filter gain in the passband is unity or 0 dB. You can also use MATLAB command "roots" to check for the poles that are p_1=-100 rad/s, and p_2=-300 rad/s.
Design the simplest all-NOR circuit that has three inputs, x1, x2, and x3, which produces an outpt value of 1 whenever exactly one or two of the inpuit variables have the value 1; otherwise, the output has to be 0.
