SSB stands for Single Side Band. In SSB, the carrier and one of the side bands are eliminated before transmission. This enables the power amplifier to focus all transmitter energy on the single remaining sideband. SSB allows greater range with less power consumption. SSB also enables more efficient utilization of the radio frequency spectrum. The SSB receiver reinserts the proper carrier after reception and before modulation.

LNB (Low Noise Block) is the receiving end of a satellite dish. The LNB must be pointing directly to the satellite overhead in orbit to receive the strongest and clearest signal. There are many types of satellite dishes available, some of them are installed in a fixed position, others are installed so that they can move regularly. The type of satellite that the user would like to receive signals from usually determines this. As with a normal TV antenna, it may be required for the user to adjust the LNB Read More

One of the many benefits of a technological age is the ability to use software in the aid of business. A fine example of business software is OLAP. OLAP, or Online Analytical Processing, is used to collect fact sheets for various aspects of your business and then allow for the user to ask specific questions and receive answers in a quick, efficient manner. In this article, we will explain how OLAP works and identify a number of OLAP services. What is OLAP Software OLAP software uses what is known as Read More

A flying car is a personal flying machine that does not require special equipment, runways, or traffic routes. Flying cars differ from commercial aircraft such as airliners, helicopters, and jets. Flying cars are designed to hold only a few people and are no larger than a regular automobile. While flying car designs have been in the works for over a century, it is still unclear whether a flying car would operate via magnetic forces, anti-gravity, or standard aerodynamics. What is clear, however, is that society is on the verge of Read More

JDBC (Java Data Base Connectivity) is an API (Application Programming Interface) for connecting to databases from the Java environment. JDBC is an alternative to ODBC. JDBC's Java interface is more comfortable to Java programmers than ODBC's C language interface. JDBC is included with both J2SE and J2EE. If no JDBC driver is available for your needs, a JDBC-ODBC bridge may be used to connect to an ODBC driver via the JDBC API. Java 2 includes a JDBC-ODBC bridge for Solaris and Microsoft Windows.

The safe mode boot option was first introduced with Windows 95. It is a problem-solving mode of an operating system. Safe Mode and other Safe Boot options menu can be accessed by pressing the F8 key on the keyboard, while the computer is restarting. What is Safe Mode? When the operating system fails to boot normally,  safe mode can help you identify and resolve the issues that are preventing the OS from working normally. Issues that need booting to safe mode are typically major ones, such as disk corruption, installation Read More

The Frequency-Hopping Spread Spectrum (FHSS) is a means of transmitting radio signals by shifting a carrier across a number of channels with a pseudorandom sequence that the sending and receiving station knows beforehand. The method is used as a multiple access process in the FH-CDMA (Frequency Hopping Code Division Multiple Access) transmission scheme. What Are the Advantages of Spread-Spectrum Transmission? The frequency hopping spread spectrum over a fixed-frequency transmission method has 3 primary advantages: #1 – The method is very resistant to narrow band interference since the spread signal causes Read More

The level of access that one has to his/her Windows machine depends on whether the Windows Login interface is enabled or disabled. When the logon screen is enabled, the user is prompted to select an account username and put in a password for the account selected. This allows users to access a single computer via many accounts when it has been preconfigured for this purpose. Individuals who are the sole users of their computer prefer to disable the Windows logon screen. They may also use a single account and therefore Read More

The term stereoscopic vision refers to the human ability to view with both eyes in similar, but slightly different ways. This allows humans to judge distance, which develops their ability to have true depth perception. Historically, the human’s ability to view the world through stereoscopic sight has given him/her a significant advantage over entities and animals in the wild that do not possess this capability. How does Stereoscopic Vision Work? For people and animals that have stereoscopic vision, each eye sees a similar, but slightly different image. This difference is Read More

iTunes is an easy-to-use digital media application developed by Apple in 2001. It allows the user to play and organize music and video on a personal computer and to manage the contents of their iPod. iTunes is available as a free download. Its amazing features allow users to import music from CDs, listen to and view podcasts, buy music online, listen to music on the Internet and across networks, etc. However, some users may want to have more functionality than that offered by iTunes and may need to look for Read More
