Determine the figure of merit in dB for a satellite earth station with the following specifications:
Antenna Gain - 35 dBi
Reflector noise temperature - 22K
LNA noise temp - 42K
Noise temp (various components) -2K
A Fabry-Perot interferometer is to be used to resolve the mode structure of a He-Ne laser operating at 632.8 nm. The frequency separation between the modes is 150 MHz. The plates are separated by an air gap and have a reflectance of r^2=0.999.
You wish to measure the properties of a high-quality low-pass filter but you only have a normal oscilloscope to observe the Si-like pulse response. How can you deduce the features of the filter from this?
The forces 20N,30N,40N,50N and 60N are acting on one of the angular points of a regular hexagon towards the other five angular points taken in order. Find the magnitude and direction of resultant force
The specificationof the desired low pass filter are A min=23 dB, A max=5dB, P=02and S=0.6. Design a Butterworth digital filter using bilinear transformation.
Write a total mass balance on the tank contents convert it to an equation for dV/dt. and provide an initial condition. Then write a potassium chloride balance, convert it to an equation of the form dC/dt = f(C, V), and provide an initial condition..
Design a summing amplifier that produces an output Vout = (5/2)V1+(5/3)V2 - 4V3 . Draw the complete schematic and pick the appropriate component values. The smallest resistor in the circuit should be R
Determine the periods and find exponential fourier series coeffecients of functions. A.) f(t) = 2(cost)(cos2t) B.) g(t) = 3 + 2e^-j2t + 2e^j2t + 2cos4t C.) h(t) = 4
Evaluate the response for a suitable length of time so that the response reaches steady state. Then, determine the magnitude and phase of the output v0 (t) , and compare to the magnitude and phase of your Bode plots at frequency 5,500 rad/sec.
How the problem of interfacing IC logic families that have different supply voltages (VCCs) can be solved? What are the advantages of Totem Pole Output? What are the disadvantages of Totem Pole Output?
Determine the magnitude of the scattering parameters for this circuit, using a 30 Ω characteristic impedance.
A conducting filament containing a small 400 ohm resistor is formed into a square loop on the x-y plane as explained in the previous problem. Find I at t = 2*10^-4 sec if (a) \(B = 3cos(12000\pi t)a_z T\)
Graded-index separate confinement double heterostructure (GRIN-SCH) InGaAs/GaAs lasers with various cavity lengths were tested in the lab. The 100m wide oxide strip lasers consists of two pairs of 10nm In0.2Ga0.8As quantum-well (QW).
