A reciprocal 2 port microwave device has vswr of 1.5 andan insertion loss of 2db .Find the magnitudes of S- parameters forthe device.
What is the maximum message bandwith for which the system operates satisfactorily? Determine the output signal to quantizing noise ratio when a full-load sinusoidal modulating wave of frequency 1 MHz is applied to the input.
A 10 kW laser beam pointing at the ship is turned on at t=0. What speed the ship will attain in 1 day assuming that the surface of the ship is perfectly reflective and perpendicular tot the beam.
n electrical heater is connected to a constant 250-V sourceand absorbs 1000W. Subsequently, the heater is connected to a constant 220-Vsource. What power does it absorb from the 220-V source. What is the resistance of the heate.
What causes the current gain to decrease both in the case of a low collector current and at a high collector current?
The magnetization graph taken at 1800 rpm of a 6 kW, 120 V, 50 A, 1800 rpm, dc generator is attached below. Field resistance is 20 ohms and armature resistance is .18 ohms. Find: As a seperately excited generator
When finding the inverse Z-transform of functions with z-1 terms in the numerator, the fact that z-1 can be thought of as a delay operator can be used to simplify the computation. Consider X(z) =1 - z-10 / 1 - z-1
Let Un be a sequence of iid zero-mean,unit-variance Gaussian random variables. A "low pass filter" takes the sequence Un and produces the sequence Xn =1/2 ( Un +Un-1) a.) Does this sequence converge in the mean square sense
Calculate the following for this circuit: PR1 W PR2 W PR3 W PR4 W PD = PR1 + PR2 + PR3 + PR4 W 6. Verify that the total power dissipated in the resistors, PD is equal to the power supplied by the DC source, PS.
Help with problem in Control signal processing class, Consider the unity-feedback control system whose open-loop transfer function is
An initially uncharged 2 microfarad capacitor is connected in series with a 10 k-ohm resistor and a 12 V battery. Find the charge and voltage on the capacitor after a very long time and find the voltage and charge on the capacitor after one time co..
A summary of the nuclear reactions that power our sun can be written as 4p 4He + 2e-, with masses of 938.272 MeV/c2 for p, 3727.38 MeV/c2 for helium, and 0.511 MeV/c2 for electrons.
discharge a capacitor of 1mF charged with a voltage of 1 volt we connect it, at time t = 0, with a esistor of R ohm. When we measure the voltage we find it to be V(r) (t) = e ^(-t) u(t). Determine the resistance of R. If the capacitor has a capaci..
