    fundamental differences of analog and digital signalling. Baher (2001, p. 2) states that the natural world we live in, as well as most artificial sources, produce signals which we have grown accustomed to consider mainly of the analog type. This means that the signal f (t) is defined, somehow, for all values of the continuous variable t, and its amplitude can assume any value of a continuous range. Such a signal is referred to as an analog signal. In contrast to analog signals, other signals are

    The Transition from Analog Television to Digital Television The transition from analog television to digital television is an issue that is becoming more and more prevalent today. In 1996 the FCC (Federal Communications Commission) ruled that until 2006 or when digital television reaches 85 percent of all American households (whichever comes later) broadcasters can keep their analog spectrum free-of-charge. They decided that after that all television broadcasts must be made digital(Leopold)

    and in few areas is it as prevalent as it is in the music industry. Today’s analog-to-digital converters allow us to accurately store the physical, analog phenomena of sound as digital data, with high fidelity and perfect reproduction quality [1]. Digital audio storage is far more practical than analog audio storage for both the consumer and the professional alike. Digital audio is not vulnerable to noise, unlike analog audio where noise is not only prevalent but machine-indistinguishable from the

    Introduction to ADC: Analog refers to physical quantities that vary continuously instead of discretely. The physical phenomena typically involve analog signals. We have many examples like speed, temperature, pressure, voltage, etc. But microprocessors work with digital quantities, means the values which are taken from discrete domain. To interact analog systems with digital systems or digital systems with analog systems conversion is needed. There are 2 types of conversions: (1) Analog to digital converters

    TIC: THERMAL IMAGING CAMERA In the mid-1980's, the thermal imaging camera (TIC) was introduced into the firefighting market as another tool to aide in their ability to save lives, including their fellow firefighters. However, since its introduction there have been numerous discussions whether or not the TIC has a place in the firefighter's arsenal of tools. It is claimed that the TIC is "...one of the most spectacular applications of technology introduced into the fire service since the steam engine

    because it is easier to encrypt than analog. Mary Jane Dittmar, of Fire Engineering magazine, describes the technologies as working by "converting a voice into binary information and then compressing it. Through modulation and encoding formats, the analog information is converted to digital data, compressed, and then converted back again, while still maintaining acceptable levels of voice quality. Digital technology is clearer and easier to understand than analog technology because background ...

    impatient group. They are starving for a faster way of connecting to the ‘net. Until now home users have had to suffer with the slow connections available with analog modems or spend a relatively large amount on having a digital line, such as ISDN, installed and then continue paying a lot for the monthly charges associated with such lines. Standard analog modems have always been hindered by the bandwidth they are allowed to use. Standard voice grade phone lines use the frequency spectrum between 0khz and
