Wiring diagrams use standard symbols for wiring devices, usually different from those used on schematic diagrams. The electrical symbols not only show where something is to be installed, but also what type of device is being installed. For example, a surface ceiling light is shown by one symbol, a recessed ceiling light has a different symbol, and a surface fluorescent light has another symbol. Each type of switch has a different symbol and so do the various outlets. There are symbols that show the location of smoke detectors, the doorbell chime, and thermostat. On large projects symbols may be numbered to show, for example, the panel board and circuit to which the device connects, and also to identify which of several types of fixture are to be installed at that location.

For dynamic signals, the transfer function cannot in general be described simply. However, if the input is a sinusoidal signal then the output must also be a sinusoidal signal with the same frequency but possibly a different amplitude and phase. In other words, a linear system can only modify the amplitude and phase of a sinusoidal input.
By Bertille Solange. Power. Published at Wednesday, December 20th 2017, 14:46:18 PM. In shunt regulation a resistor is typically placed in series with the load and the unregulated voltage. The resistor is small enough so that the load could always receive somewhat more than the maximum current it would ever need. The shunt regulator is placed across the load and conducts excess current around the load such that the voltage across the load remains a constant as the load draws the actual current at any given time. A common shunt regulator is a Zener diode which is an example of an open loop system. Feedback control can also be used to drive the current through the control element (a transistor) across the load. Shunt regulators are generally only used for low power applications because they can be very inefficient. However, shunt regulators have an inherent fault current limiting feature and also can regulate even if the load is forcing current into the regulator rather than drawing current from it. Shunt regulators also have an interesting feature that the input current is constant – independent of load current (except if a load fault occurs – but that is a special case not in normal operation). Thus shunt regulators are very good at isolating a load with rapid and large current fluctuations.

Examples of electronic output devices include computer monitors, LCD alphanumeric panels (as on a calculator), small lamps or light-emitting diodes (LED), etc. Digilent boards include different output devices, but all of them include some number of individual LED, and seven-segment LED displays that can display the digits 0-9 in each digit position (each segment in the seven-segment display contains a single LED). LED are two-terminal semiconductor devices that conduct current in only one direction (from the anode to the cathode). The small LED chips are secured inside a plastic housing, and they emit light at a givenfrequency (RED, YELLOW, etc.) when a small electric current (typically 10mA to 25mA) flows through them.

A wiring diagram is sometimes helpful to illustrate how a schematic can be realized in a prototype or production environment. A proper wiring diagram will be labeled and show connections in a way that prevents confusion about how connections are made. Typically they are designed for end-users or installers. They focus on connections rather than components
By Bertille Solange. Amplifier. Published at Wednesday, December 20th 2017, 14:39:29 PM. Generally, amplifiers can be sub-divided into two distinct types depending upon their power or voltage gain. One type is called the Small Signal Amplifier which include pre-amplifiers, instrumentation amplifiers etc. Small signal amplifies are designed to amplify very small signal voltage levels of only a few micro-volts (μV) from sensors or audio signals.

Completing an electrical engineering degree and then getting a job in the field means you will see a lot a lot a lot of these schematics. It’s important to understand exactly what is going on with these. While they can (and will) get very complex, these are just a few of the common graphics to get your footing on.
