Assignment Questions 1. Why is Airbus interested in building the A3XX? What are its objectives? Because of the increasing demand in air transportation and rising traffic in many airports‚ VLA segment will grow up significantly‚ so this will be a huge advantage for Airbus. Airbus’s researches show that compared to others‚ A3XX will help Airbus to get more profit. 2. How many aircraft does Airbus need to sell in order to break even on the investment? Is this number greater or less than

System designer for wireless communication system need to cope the problemS how to increase the number of user and services that are supported in limited radio frequency bandwidth in define area. This requirement can be achieved if system design engineers overcome the problem of bandwidth efficiency by increasing the data transmission rate and capacity to use multi-level modulation and demodulation

relationship between the transmission of the car‚ its size (class)‚ the year of manufacture‚ the number of cylinders and engine displacement and fuel efficiency. Cars that can drive more miles per gallon of fuel used will be the most fuel-efficient. Inversely‚ cars that consume a lot of fuel will not be fuel-efficient. Question 1- ------------------------------------------------- Transmission vs. Fuel Efficiency In order to analyze the relationship between the transmission cars and fuel efficiency

represents‚ either 0 or 1. Digital signals are complex waveforms that can be described as a discontinuous waveform having a finite range of levels. You can recognise a digital signal by the wave created‚ if the wave keeps going up and down in straight lines and forms squares and rectangles these are digital signals. Digital signals assume two states (logic 0 and logic 1). Where the signal changes from one state to another‚ the signal can be said to be discontinuous. As the signal state changes from
