A queue is a First In First Out digital logic design that saves the elements in an array such that elements are added from one end (head) and removed from the other end (tail). For example, if user saves elements ‘2’, ‘4’, ‘6’, ‘8’ one by one the queue will return ‘2’, ‘4’, ‘6’ and ‘8’ one by one when required.
Functionality Required:
- Storage of 10 integers ranging from (0)10 to (15)10
- Insert element in queue, if queue is already full then inform the user
- Remove element from queue, if queue is empty then inform the user
- User friendly interface

Suppose there is a FM radio receiver, where the whole system is heated up with time due to faulty circuit components.
i) What are the changes may occur in the system due to the changes in temperature? Explain.
ii) Draw and explain the effects on skewness and kurtosis in Gaussian distribution of thermal noise when there are changes in temperature in the FM radio receiver system.

An accelerometer is measuring a structure as described below:

Damping ratio of accelerometer = 0.65

Highest frequency measured by the accelerometer = 6000 hz

Natural frequency of the accelerometer = 18000 hz

What is the percentage error in the accelerometer at the highest frequency it can measure? (Type in a two-decimal number that represents a percentage)

A delay difference of ‘x’ns between the slowest and fastest fiber with a core refractive index of 1.5 and refractive index difference of 2%. Estimate the following
The length of the optical fiber link
RMS pulse broadening due to intermodal dispersion link
Bandwidth –length product for the maximum bit rate.

I have a circuit with two resistors in series then three following in parallel after that, r1 is 100 ohms r2 is 270 ohms, the resistors in parallel are 1000 ohms 1200 ohms and 2700 ohms, the supply voltage is 12v

i must calculate :
the supply current
the voltage dropped across each resistor
the current flowing through each of the parallel resistors

A three-phase, 415 V load takes a line current of 800 A from a 3300/415V delta – star transformer. The 3300V system is supplied from an 11000/3300V star – star transformer. Draw the circuit diagram and, assuming no losses, find both line and phase values of voltages and currents in each part of the circuit. What will be the turns ratios of both transformers?

A skier weighing 55.0 kg starts from rest at the top of a frictionless incline
of height 20.0m, as shown in Figure Q1(b). At the bottom of the incline, she
encounters a horizontal surface where the coefficient of kinetic friction
between skis and snow is 0.210 instead of being assumed frictionless
as for the slope. The angle of the triagle is 20 deegrees.
(Assume gravitational acceleration is 9.8 m/s2)
(i) Calculate her speed at the bottom of the incline.
(ii) Calculate the friction force on the horizontal surface.
(iii) Calculate the energy loss to the horizontal surface when the skier
stops on the horizontal surface.
(iv) Determine how far she travels on the horizontal surface before
coming to rest.
(v) Find the distance the skier travels along the horizontal surface
before coming to rest if the incline also has a coefficient of kinetic
friction equal to 0.210.

What is the ground voltage with neutral? Why does it occur? How many Volts should it be? What can be done to prevent and eliminate it?
