The another advantage of this ADC is it is less complex because the DAC circuit is not used in the ADC architecture. The main drawback of this ADC is that it is only suitable for low bandwidth input signals. 4.2 Summary of ADC Architectures All the most popular ADC architectures have been explained in detail in previous sections. The flash ADC architecture is the fastest, the SAR ADC gives low power applications, the ∑∆ ADC is useful for high resolution…

and harmonic components in voltage/current signal using FFT, observed the stylized spectrum of distorted signal in digital analyzer or DSO with power system frequency and design digital filter to minimize the harmonics of power systems. Keywords - Harmonics, non-linear loads,…

Music is something that everyone in the world can relate to. All cultures, races, and religions listen to music. The main way that people listen to music now is through their phones or with their computers. Anytime there is a social event, there is music playing in the back ground with the use of speakers. Speakers are the technology used today for most of your music needs because they can be connected to any type of phone. There is nothing worse than when you are at a party and suddenly there…

Often times iconic scenes in a movie will have amazing music, sound effects and vocals to tie the whole scene together, and with all of these, visuals are not really needed, they will only give a crystal clear image of what the director has already portrayed with sound. One example could be the shower scene in Psycho; if you turn off the screen and only listen to the sound; an almost crystal clear visual is made because you can hear what is actually going on. Another perfect example is the…

After teaching my two lessons on phonemic segmentation and observing the two students during whole class instruction I have drawn various conclusions on both the students strengths and weaknesses. Student A excels at being able to tap out sounds within a three sound word, as student B is able to tap out the individual sounds of words with 4-5 sounds in them. These activities however acted as review for the students being as they were exposed to these concepts in kindergarten. During whole class…

The Quaid-e-Awam University of Engineering, Sciences & Technology Nawabshah (Q.U.E.S.T) at one time called Mehran University of Engineering and Technology, Nawabshah is set just outside town of Nawabshah near aerodrome and is touch an area of 457 sections of land on either side of the most Sakrand street. Right away, it comprises of 3 instructive divisions. Segment A homes the divisions of connected science, physical science Engineering, tablet Systems Engineering, Institute of learning…

1.1 Definition Digital describes electronic technology that generates, stores, and processes data in term of two states which positive and nonpositive. Positive is expressed or represented by the number one while non-positive by the number of 0. Thus data transmitted or stored with digital technology is expressed as a string of 0’s and 1’s. Each of these state digits is referred to as a bit. Literacy is the quality or state of being literate, especially the ability to read and write, to…

1. Introduction The purpose of this experiment was to gain an understanding of how to use a signal generator, acquire data, understand the concept of a Low Pass Filter, gain knowledge of time domain sampling and sample rate, learn how to analyze and present data in MATLAB, as well as learn how to calibrate a microphone and record sound pressure data. To accomplish this the role of an electronics technician whose responsibility was to validate the performance of data acquisition equipment that…

For most of human existence, people have practiced and created art to express their thoughts and their interpretations of the world around them. One of the many art forms we have created along the way is music. For centuries, music was made by a skilled person or group of people playing instruments, whether it be a piano performance or an entire orchestra. In the twentieth-century, however, music began to change. With the help of digital technology, new ways to create music emerged. One of these…

distinct value of phase shift of a carrier. The QPSK signal is represented as. Since there are 4 phases it is called as 4-PSK or Quadrature PSK systems [6][7]. 3. QAM: QAM improves the noise immunity of the system by allowing the signal vectors to differ, not only in their phase but also in amplitudes. It utilizes carrier phase shifting and synchronous detection to permit two DSB signals to occupy the same frequency band. The two DSB signals are orthogonal to each other. IV. NOISE AND…
