a) What is the coupling ratio b) What are the insertion lossesc) Find the excess loss of the coupler
2- DWDM optical transmission system is designed to have 100-GHz channel spacings. how many wavelength channels can be utilized in the 1536 to 1556 nm spectral band?
In the digital communication link the data rate is 500 kb/s. The modulator generates the binary FSK signal. a) Determine the transmitted bandwidth if the difference between two frequencies fc1 - fc0 = 300 kHz
Ten multimode glass fibers (n1 = 1.48, n2 = 1.45) are spliced together. Each fiber is 2 km long and has a loss rate 2-dB/km. Each splice adds 1 dB of loss. If the output power of the source is 7 dBm and radiates uniformly in a 60 degree half cone
The effective water head for a 100 MW station is 220 metres. The station supplies full loadfor 12 hours a day. If the overall efficiency of the station is 86.4%,find the volume of water used.
A Polyester capacitor with a leakage specification of 5x109 O -µ F is used in a circuit. The voltage across this capacitor is 100 volts D.C. and the capacitance is 0.1µ F find the leakage current.
What is the perceived colour if the energy of light is same corresponding to red green and blue,and zero at other frequencies what about red and green frequencies only
Two voltage waves of equal amplitude, V0, and frequency w, propagate in the forward z direction in a lossless transmission line of characteristic impedence Z0. One waves is phase-shifted from the other by \o radians.
The base class must also have a virtual print() function that displays the class name. Randomly assign print functions in three other classes that display the class name. Create 7 pointers of the base class and have them point to all the classes.
A minority voting circuit makes a decision based on the minority of votes. The logic receives THREE inputs x, y, and z.Together, these input variables are the binary representation ofthe number of members who vote "yes" out of 7 total members.
Given the starting address for the TC0 Interrupt is to become $5000. Write the assembly instruction necessary to place this ISR address into the interrupt vector table and then unmask the interrupt (assembly only).
A one-dimensional infinite potential well with a width of 12 Ao contains an electron. (a) Calculate the first two energy levels that the electron may occupy. (b) If an electron drops from the second energy level to the first, what is the wavelengt..
The system contains a door sensor, a window sensor, and a key activation switch. If the switch is on, opening the window will set off the alarm immediately. Opening the door will start a 30 second timer.
