A laser diode has a threshold current of 12 mA and emits at 3 mW/mA rate. A diode current of 15 + 5sin ωt (mA) produces an optical signal, which is coupled into a SI fiber having a loss rate of 2-dB/km and a numerical aperture of 0.24. After 10-km propagation length, an erbium-doped fiber amplifier having a noise figure of 6 and a gain of 15 dB amplifies the signal. The signal output of laser has a 50-dB signal to noise ratio (SNR). Compute the signal power (in dBm) and signal to noise ratio (in dB) at the amplifier's output.
A tractor-trailer truck driver friend often delivers to companies that do not have a fork truck or loading dock. She wants to install a lift-gate on her trailer so she can load and unload her truck without a fork truck.
find the complete functions, p(t) and w(t) supplied by the element, not just a number, and graph p(t) and w(t). Choose appropriate intervals of time for your graphs. Assume that both v(t) and i(t) are zero for t
In addition, assume that your house is the only one using electric power. At a substation the primary of a step-down transformer (turns ratio = 1:26) receives the voltage from the high-voltage transmission line.
For a complex load of 100 + 25 j ohm. find the matching circuit consist of ideal capacitor and/or inductor to match the load to 50 ohm impedance at 500MHz. The solution should include circuit schematic and values of each component
Generator 1: 10 MVA, 11 kV, X1s=1.6 per unit on a base using generator A's rated voltage and power Generator 2: 20 MVA, 11 kV, X2s=1.2 per unit on a base using generator B's rated voltage and power Impedance of Line 1
Assume that the load is star connected with the neutral disconnected. Each phase has a series RL load with R = 5 ohms and L = 20 mH. Plot the neutral voltage Plot the phase to neutral voltage for phase a.
A solar pond consists of a thin layer of fresh water floating ontop of a denser later of salt water. When the salty layer absorbssun light, it becomes hot, to 140 degrees C. The ambient temp isassumed to be 20 degrees C.
Given a three phase motor: 5 hp, 3515 rpm, 230V, 10A, efficiency = 75%; derive the per-pharse equivalent circuit of the motor.
