Free To Air Satellite

Free to air satellite receivers, or FTA are becoming more popular and their usage is growing. The following are the basic facts about this device. What the Receivers are The devices are complex, but generally they work the following way. The receivers are designed to take in information and data from the FTA satellites. These transmissions are not encoded. The data is usually in MPEG – 2 format. The receiver is able to get the data by using a video codec compatible with MPEG 2. When the data is relayed, the transmission is usually relayed at UHF or VHF TV

How to Use a Multimeter

The Multimeter is a tool used by electronics related individual in measuring voltage, current, and resistance. A mulitmeter can be digital (digital multimeter or DMM) or analog (analog multimeter or DVOM). Using the multimeter can be very complicated especially to those who know nothing about electronics. However, with the information provided in this article, we are hopeful that one can have an idea on how to use a multimeter. Parts of an Analog Multimeter Meter Section – this part consist of the pointer and scales. The movement of the pointers allows the users to read the voltage, value, current value,

Free Satellite Images

A special image that is consisted of photographs of planets like the Earth taken by artificial satellites, satellite imagery has useful applications in various areas of studies like biodiversity conservation, education, military intelligence, agriculture, warfare and forestry. This imagery has two kinds of resolution, namely geometric and radiometric. Geometric resolution is the ability of the satellite sensor to provide an image of the surface of the earth using the Ground Sample Distance system. On the other hand, radiometric resolution provides an image that is commonly expressed in different grayscale levels like 16-bit, 12-bit, 11-bit and 8-bit. Free Satellite Images Where
