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.a) What is the coefficient of finesse and finesse of the instrument?b) What is the resolving power required?c) What plate spacing is required?d) What is the free spectral range of the instrument in these conditions?e) What is the minimum resolvable wavelength interval under these conditions?
A shunt DC motor has RA = 0.7-ohm and VT =429.6 V. For an output power of 50.4 hp, we have nm = 1,452 rpm and IA = 110.8 A. The field current remains constant for all parts of this problem. Find the rotational power loss in watts.
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).
what are the different methods used in frequency response analysis
If the motor is driving a load whose torque requirement remains constant at 3Nm, independent of speed. Calculate the armature voltage Va to be applied in steady state, if the load to be driven at 1500RPM.
Write the phasor expression I for the following current using a cosine reference a.)i(t) = I0cos(ωt - π/6): b.) i(t) = I0sin(ωt + π/3):
Four frequencies are applied at the input of a non-linear amplifier. Write down all of the frequency components at the output of the non-linear device. Write down only the first three harmonics. Frequencies of 1205Khz, 1200Khz, 1195Khz
If a third attempt is made within 20 seconds, a waiting period of 20 seconds is required before additional attempts can be made to start the motor. While waiitng to make additional attempts to start the motor.
After having the VHDL code tested, make sure to run ISE-Simulator. Since there are 4 inputs, modify the test-bench code for all sixteen possibilities. View the waveform and test it against your truth table.
A candidate material for a turbine blade application oxidizes by diffusion of metal atoms through the oxide to the metal surface, where metal and oxygen react to form the oxide. After 10 hours at 550*C, an oxide layer 8µm thick has formed.
Suppose that the type of key in a hashing application you are implementing is String. Design, implement, and test a hash function that converts a key to a hash value. Assume that the size of the hash table is a prime number.
Design a logic circuit with 8-inputs and 4-outputs. The circuit should count the number of 1's in the input. The output should be values between 0 and 8.
Developing secret codes has interested people for centuries. A simple coding scheme can be developed by replacing each character in a text file by another character that is a fixed number of positions away in the collating sequence.
