Tracking(locked) ABSTRACT We were assigned to build a phase locked loop frequency synthesiser. The purpose is to help students to gain experience in hardware construction‚ coordinated teamwork and project management. The design uses 74HC4046‚ a PLL integrated circuit (IC) made from CMOS technology A PLL is a closed loop frequency system that locks the phase of an output signal to an input reference signal. The term “lock” refers to a constant or zero phase difference between two signals. The signal from

THE IMPLEMENTATION PHASE OF A CONSULTING PROCESS The implementation phase is the FOURTH phase of the consulting process. The basic purpose of any consulting assignment is to implement changes that are real improvements from the client’s point of view. Implementation is easy where the consultant and the client collaborated closely during the earlier phases‚ as the client can rarely reject proposals that are the product of joint work. Implementation works well if corrective measures were

Abstract: Phase absence is a very common and severe problem in any industry‚ home or office. Many times one or two phases may not be live in three phase supply. Because of this‚ many times‚ some electrical appliances will be on in one room and OFF in another room. This creates a big disturbance to our routine work. This project is designed to check the availability of any live phase‚ and the load will be connected to the particular live phase only. Even a single phase is available‚ and then also

environmental risks‚ the phase one environmental site assessment (ESA) can help determine whether a property may have been contaminated by current or previous activities. The purpose of the environmental assessment is to determine if there is a contamination on the property which may affect the environment or the people who are using the property. It is commonly required when there’s a transaction in the ownership of the property‚ when applying for a building permit or when changes in zoning or usage of

1 A Voltage-Controlled Oscillator (VCO) is a circuit that provides a varying output signal (typically of square-wave or triangular-wave form) whose frequency can be adjusted over a range controlled by a dc voltage. An example of a VCO is the 566 IC unit‚ which contains circuitry to generate both squarewave and triangular-wave signals whose frequency is set by an external resistor and capacitor and then varied by an applied dc voltage. Figure (1) shows that the 566 contains current sources to charge

It ensures that businesses are efficient‚ effective and adjustable. Different organizations face a dispute in developing a Business Process Management (BPM) that is appropriate to all organizations in all circumstances. There are ten phases in the implementation of BPM: Organization strategy‚ Process architectures

currently being experienced by bookshops and what are the effects? Not many of us now will still go to bookshops and spend an afternoon to find a book you are interested to read. The Economist (2010) states that more than 50% of books were sold at some large retailer like WalMart and Target. Also‚ everything around us becoming electronic‚ Amazon starts to sell digital books online and wreaking threat to the physical-bookselling market. Problems faced by bookshops rise as the style of living changed

modulation in which the digital information is transmitted by discrete changes in frequency of the carrier signal. This technology is used for the communication system such as caller ID and emergency broadcasts [19]. The binary FSK is the simplest FSK. BFSK uses a pair of discrete frequencies to transmit binary information. The 1 and 0 is mentioned as mark frequency and space frequency. The other forms of FSK are Continuous-phase frequency-shift keying‚ Gaussian frequency-shift keying‚ Minimum-shift

Understanding Questions Directions: Answer the following questions in complete sentences. One to two sentences will not suffice. 1. Write down what your observations as you look at the ball at different positions in its orbit around your head. The ball goes thru the same phases that the moon would go through. The way I started would be the same as the full moon (the ball
