H Bridge is a simple electronic circuit which enables us to apply voltage to load in either direction. It is commonly used in robotics application to control DC Motors. By using H Bridge we can run DC Motor in clockwise or anticlockwise directions. This circuit is also used to produce alternating waveforms in inverters.
D Flip Flop is primarily meant to provide delay as the output of this Flip Flop is same as the input. D Flip Flop can easily be made by using a SR Flip Flop or JK Flip Flop. But sometimes designers may be required to design other Flip Flops by using D Flip Flop. Here we discuss how to convert a D Flip Flop into JK and SR Flip Flops. The first thing that needs to be done for converting one...
The giant chip maker Intel has finally released its 3ed generation chips named Ivy Bridge. They says that the new microprocessor chips used fundamentally different technology. These chips comes with 3D Transistors and are manufactured at 22nm process. The new technology will ensure high processing speed along with power saving. The chip makers keep the pace of Moore's law by making the new chips using 3d transistor technology along with other advanced capabilities. We can hope that, customers will certainly welcome the...
We all know that electrons are good at processing information, but they are incapable of carrying information over long distances. On the other hand, Photons can carry information all around the planet but their processing is hectic. So we use electrons for processing and photons for long distance data transmission. Thus we need significant amount of power to convert optical information to electronic and vice versa. Hence there is no wonder in the fact that researchers pay significant interest in developing...
A relay is an electromagnetic switch used to switch High Voltage or Current using low power circuits. For example, we can use it for controlling home appliances with a normal low voltage electronic circuit. Electromagnetic relays uses an electromagnet to operate a switching mechanism mechanically. It also provides isolation between low power circuit and high power circuits. Relay Internal Diagram The construction and working of a relay can be understood from the above diagram. The main part of a relay is the electromagnet. The...
Recently, the scientists from the National Institute of Standards and Technology (NIST) along with an international research team delineated the possibility of a new class of sterilizable, flexible, organic electronic materials for medical applications by proving the stability of a novel and rugged thin-film membrane at high temperatures. The work conducted using a low-energy X-ray beam line, at the National Synchrotron Light Source (NSLS) in Brookhaven, N.Y., was supported by an international team led by...
SR Flip Flop is the basis of all other Flip Flop designs. But it has a major drawback that the output becomes not defined whenever both inputs S=R=1. Here we discuss how to convert a SR Flip Flop into JK and D Flip Flops. As you may know for T Flip Flop, both the inputs are same, which is a limitation in case both inputs are 1. So T Flip Flop cannot be realised here. The first thing that needs to...
A crystal oscillator is an electronic oscillator circuit which uses inverse piezoelectric effect, ie when electric field is applied across certain materials it produces mechanical deformation. Thus it uses mechanical resonance of a vibrating crystal of piezoelectric materiel to create an electric signal with very precise frequency. They have high stability, quality factor, small size and low cost and this makes them superior over other resonators like LC circuit, ceramic resonator, turning forks etc. This image show a 8MHz crystal oscillator commonly used in microcontrollers and microprocessors. Although...
