Electronic Devices: Relays
http://electronic-device.blogspot.com/2008/04/relays.html
Sunday, April 27, 2008. A relay can have many different types of contacts. The relay shown in figure 3-19 has contacts known as "break-make" contacts because they break one circuit and make another when the relay is energized. Figure 3-20 shows five different combinations of relay contacts and the names given to each. Posted by Dadang Supriatna. Subscribe to: Post Comments (Atom). Enter your search terms.

Electronic Devices: Fiber Optic Sensors
http://electronic-device.blogspot.com/2009/10/fiber-optic-sensors.html
Monday, October 26, 2009. What are fiber optic sensors? The fundamental characteristic of all fiber optic sensors is that they depend on some optical properties, such as intensity, phase, state of polarization and wavelength, to be modulated by measurands. Measurands could be pressure, temperature, electromagnetic field or displacement. 1 Intrinsic Fiber Sensors. Because of the refractive index change, lights that travel through the fiber are affected accordingly. The changes in light properties, suc...

Electronic Devices: Opamps: Operational Amplifiers
http://electronic-device.blogspot.com/2008/03/opamps-operational-amplifiers.html
Friday, March 28, 2008. Operational amplifiers, often known as opamps, are nifty little integrated circuits that contain several transistors. These transistors are used to amplify or attenuate a signal, depending on the circuit that the opamp is placed in. Why use an opamp when you can use a transistor? The first step in designing your circuit is to determine the gain you will need. Let’s assume that the signal from your sensor has a peak of 5 millivolts. In that...To find the gain you need, you d...

Electronic Devices: Dioda
http://electronic-device.blogspot.com/2008/03/dioda.html
Sunday, March 2, 2008. Figure 1.1: Diode Schematic Symbol and Casing. A diode is best described as a one way valve, since it only allows current to flow from anode to cathode. For example, if you applied a reverse bias to the diode with a magnitude of 5 volts, current would not flow. If you applied 5 volts with a positive bias, current would flow. Why is a diode useful?

Electronic Devices: Transistor
http://electronic-device.blogspot.com/2008/03/transistor.html
Sunday, March 9, 2008. Transistors are electronic switching devices, which are the basis of nearly all electronic circuits. This page will give a brief outline of what they are, as well as different methods to interface analog transistors from digital circuitry. The simple explanation of a transistor is that it is a combination of three 'doped' pieces of semi-conductor material. The piece in the middle is called the Base. In Bipolar Junction Transistors), and the outside edges are the Collector. When the...

Electronic Devices: April 2009
http://electronic-device.blogspot.com/2009_04_01_archive.html
Wednesday, April 8, 2009. Logic gates take binary values and perform functions on them, similar to the functions found in simple algebra. Binary algebra is the set of mathematical laws that are valid for binary values. A binary value can only be a 1 or a 0. 1 is a high value, representing true and high voltage. 0 is a low value, representing a false value and low voltage. The equivalent binary algebra function is B = A’, where B is the output and A is an input value. Posted by Dadang Supriatna.

Thursday, February 21, 2008. They pass DC easily, but block AC signals, exactly the opposite of capacitors. Inductors are most often found in audio electronics, power supplies, and radio tuning circuits. An inductor can easily be made by winding insulated wire around a ferrous rod. Thin gauge wire is easiest, since it can bend into smaller loops and is cheaper than large gauge wire. Posted by Dadang Supriatna. Monday, February 18, 2008. It can protect components that have a specific current rating. The r...
