A Chebyshev filter can either be analog or digital, and is an improvement on the Butterworth filter as it has a steeper roll-off and a greater passband and stopband ripple. These filters minimize overall error between actual and idealized filter characteristics for the designed range of the filter. The filter was named after Pafnuty Chebyshev, who developed the polynomials that the filter design was created from. Since there is a passband ripple in Chebyshev filters, they are not the best for all applications. Their primary purpose is to separate a Read More

Data synchronization is the process in which consistency among data from the source to the data storage location and then vice versa is achieved successfully. On top of that, the continuous consistency of the data over a period of time achieved is success for the data synchronization. Data synchronization is a process that has gained a variety of uses across a platform of applications. The Uses of Data Synchronization While there are many different uses of data synchronization, there are four that are most prevalent. They are file synchronization, version Read More

An iPad is a tablet PC that Apple produced, which allows users to combine the functionality of both a Mac and an iPhone. While an iPad is larger than an iPhone, it is extremely portable and lightweight, allowing users to take advantage of iPad apps from virtually anywhere. Although iPads are smaller than Macs, iPads have all of the same functions that are expected from personal computers. While iPads provide access to the Apple App Store, users are also able to create their own apps and share or sell them Read More

Most people send text messages from the very small keypads on their mobile phones, and most people who receive text message messages read them on the tiny screens of their mobile phones. Because of those considerations, and because many service providers limit text messages 160 characters in length, most people who use text messages learn to type their messages using a number of popular text message shortcuts. Text Message Shortcuts These are some of the more common text message shortcuts. 2D To Delete 2G4Y Too Good For You 4E Forever Read More

LinkSys is the division of the Cisco Company which manufactures some of the most widely used network routers in the world. The WRT54G, WRT160N, and WRT310N series are the most popular with the WRT54G being the first model deployed that supported third-party firmware. The current generation of LinkSys routers support the draft 802.11N wireless standard that provides an increased throughput of 270Mbit/s when communicating with other 802.11n compatible devices. As the capabilities of home networking devices have increased, so has the ability of the computers and mobile devices that consumers Read More

A MIDI interface is a device that connects MIDI devices to a computer and lets the computer record from them and plays back through them. MIDI interfaces do not pass sound or audio data through them, they pass MIDI data. Through MIDI you can connect keyboards, sound modules, samplers, effect processors and put them all under computer control. The original Musical Instrument Digital Interface (MIDI) specification defined a physical connector and message format for connecting devices and controlling them in "real time". A few years later Standard MIDI Files were Read More

In the 1980s, people noted an emerging trend called 'cocooning' in which people tend to stay at home rather than spend leisure time outside.
