This project studies how to create a real-time audio frequency spectrum analyser using a Digital Signal Processor (DSP). It also explains the theory behind digital signal processing, the DSP architecture incorporated in the board, software capabilities of the DSP and the relevant software codes used. In order to achieve a frequency spectrum analyser, signal processing algorithms such as Discrete Fourier Transform (DFT) and Fast Fourier Transform (FFT) are used and explained in detail. The DSP...
This paper deals with the VLSI Approach for design of Emergency Locator Transmitter of Aircraft with Global Positioning System (GPS) Receiver. Emergency Locator Transmitter (ELT) is an emergency equipment fitted in the air craft which will locate the position during the event of a crash. The COSPAS-SARSAT (C/S) satellite system has been providing emergency alerting from system compatible ELT for a number of years and thus, has been instrumental in saving many lives around the world. However, ...
Micromachined inertial sensors are very important sensors in any navigation systems. Inertial sensors consist of accelerometers and gyroscopes. They measure either linear acceleration as the accelerometer, or angular motion about one or several axes as the gyroscope. Until recently, medium to high performance inertial sensors were restricted to applications in which the cost of these sensors was not of essential concern, such as military and aerospace systems. The advantages of micromachining...
Introduction Solar energy is the energy generated by the sun which is converted into electricity using 'photo electric effect'. This is accomplished by using PV cells. The light may be absorbed, reflected or pass through the PV cells. However, only the absorbed light is responsible for generation of electricity. PV cells absorb the packet of light from the sun known as photons which provides energy to the electron and thus creates mobility of electron in the cell thereby generating current. A...
Strength and fault By unexpectedly climbing into superior programs mechanical apparatus, Bangalore has contested thе established monetary belief that in rank to be winning internationally in а subdivision of superior technical knowledge, there ought be а tough in thе household market in that sector. Domestically, India has one of thе least concentrations of computers and some of thе poorest phone webs in thе world. There are only seven computers for every 10,000 Indians, weighed against with ...
Investigation Of Pillar Thickness Variation Effect On Oblique Rotating Implantation (ORI)-Based Vertical Double Gate MOSFET Introduction Recent development of integrated circuit reveals that several fabrication aspects are already approaching the limit, especially when the dimensions are of nanometer scale . Furthermore, the complexity of lithography for nanoscale technology poses major technological challenge and skyrocketing manufacturing investment. In dealing with this issue, some innovat...
Abstract Bhopal disaster was the worst industrial disaster in the world. On 3rd December, approximately 40 tons of hazardous methyl isocyanate (MIC) was accidentally leaked into the densely population in Bhopal, India. Thousands of people were killed immediately in this accident and many of the survivors still suffering from respiratory illness and permanent injuries. Lack of site maintenance was the primary contributing factors to the catastrophe. However, Union Carbide Corporation tried to ...
Introduction: Fault diagnosis is the logical component of failure analysis; appropriately, its domain is that of the logical fault, or simply fault, which is an abstract representation of how an element in a defective circuit misbehaves. A description of the behavior and assumptions about the nature of a logical fault is referred to as a fault model. Many early diagnostic systems used a simple matching process, in which the signature of a fault candidate would either have to match exactly the...
Why control charts are used in industry. Control chart Control charts, also known as Shewhart charts or process-behaviour charts, in statistical process control are tools used to determine whether or not a manufacturing or business process is in a state of statistical control. Purpose To determine whether a process should undergo a formal examination for quality-related problems Overview If analysis of the control chart indicates that the process is currently under control (i.e. is stable, wi...
This part of the project will examine the Seals of a rotary system on an air craft. Investigation will be carried out on Labyrinth Seals in terms of functions, material, and size. Within this chapter implementations would be made to improve the functions of seal. A close look at how Labyrinth Seals have improved the efficiency and the components that make up the seal. Seals are used to keep substances such as grease and lubricant in, while keeping dirt, fluids, and other contaminants out. An ...
