Free-body diagrams are diagrams used to show the relative magnitude and direction of all forces acting upon an object in a given situation. A free-body diagram is a special example of the vector diagrams that were discussed in an earlier unit. These diagrams will be used throughout our study of physics. The size of the arrow in a free-body diagram reflects the magnitude of the force. The direction of the arrow shows the direction that the force is acting. Each force arrow in the diagram is labeled

A. Introduction Three phase transformers are used throughout industry to change values of three-phase voltage and current. Since three-phase power is the most common way in which power is produced‚ transmitted‚ and used‚ an understanding of how three phase transformer connections are made is essential. In this section it will discuss different types of three phase transformers connections. A three-phase transformer is constructed by winding three single-phase transformers on a single core. These

Phase Locked Loop: The phase-lock-loop (PLL) is commonly used in microprocessors to generate a clock at high frequency (Fout=2GHz for example) from an external clock at low frequency (Fref = 100MHz for example). The PLL is also used as a clock recovery circuit to generate a clock signal from a series of bits transmitted in serial without synchronization clock (Figure below). The PLL may also be found in frequency demodulation circuits‚ to transform a frequency varying waveform into a voltage.
