by a wide group of people in different financial situations. Mobile phones are a necessary convenience. They provide instant communication access wherever mobile phone service is offered. There are two options for mobile phone service: analog, and digital PCS. Analog is the more expensive option and has long been the standard for mobile phone service. Digital PCS is the newest form of phone service. It works by converting human speech into software codes and converting them to audio signals before

Comparing Analog and Digital Recording In the present time we are always coming up with better electronics, because that is what we expect. So, in the recording industry we have moved from analog to digital recording. Musicians want the best recording gear to give them the fastest, easiest, and best sounding recordings for their music. Digital recording is the newer way of recording music since analog recording, but is it always better? There are obviously definite positives of digital recording

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. Physical phenomena typically involve analog signals. We have many examples of speed, temperature, pressure, voltage, etc. But microprocessors work with digital quantities, meaning the values are taken from discrete domains. 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

for over 150 years involves a long drawn out series of chemical reactions beginning with the capture of light on silver film and ending with the fixing of the image onto paper or a transparency through the development processing. The final image is analog, which means it is composed of continuous gradients that are analogous to the gradients seen in the world around us. Digital imaging, however, requires a completely different process. The image must be captured electronically on a light sensitive

waveforms in the 6 Hz to 7000 Hz range. The sine wave is a pseudo sine wave produces by a very simple wave Shaping circuit. A digital counter can be used along with a DAC to generate analog voltage functions of time such as square wave and ramp wave. In this lab, we were to design and build a circuit that generates an analog square wave and a saw-tooth (ramp) wave of voltage, using a counter and DAC/. 3. Design Process While working on this project, we thought of alternatives that would increase efficiency

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 ...
