Introduction Many electronic devices today communicate with each other externally and internally. The information in these devices can be numbers‚ words‚ sounds‚ and pictures. The simplest form of this information is digital one’s and zero’s. Sequences of one’s and zero’s are used by electronic

was to shift from analog to digital electronics by purchasing digital components from an outside vendor. Since this was the industry trend‚ it would only be logical for all the divisions within the company to readily accept the project. Unfortunately for Monica‚ this was not the case. Monica faced strong opposition by Ralph Parker‚ the VP for Signal Processing Design. Parker had three important sources of power: legitimate‚ expert and coercive. As VP of Signal Processing‚ Parker’s power was legitimate:

Difference between Analog and Digital Technologies: Analog and digital signals are used to transmit information‚ usually through electric signals. In both these technologies‚ the information‚ such as any audio or video‚ is transformed into electric signals. The difference between analog and digital technologies is that in analog technology‚ information is translated into electric pulses of varying amplitude. In digital technology‚ translation of information is into binary format (zero or one)

computing devices so that they may interact with each other. Below is a chart that shows the different types of communication media. Analog and Digital Data Transmission There are a number of differences between analog and digital transmission‚ and it is important to understand how conversions between analog and digital occur. Now with the digital age taking over‚ many people think that analog transmission methods are no longer used. This is a big misconception and certainly not true. To understand

In digital signal processing‚ any irregular signal ( such as the voltage fluctuations in the wire that connects an mp3 player to a loudspeaker )‚ can be represented in Discrete Fourier Transform(DFT)‚ as a combination of pure frequencies. It’s universal in signal processing as well as can be used for applications such as the compression of images and audio files. The DFT is so prevalent

rapid development of the speech‚ audio‚ image‚ and video compression methods‚ currently it is not a difficult task to spread digital multimedia over Internet. This makes the protections of digital intellectual property rights and content authentications have been a serious problem. Hence the technology of digital watermarking is received a large deal of attention. Generally‚ digital watermarking techniques are based on either spread spectrum methods or changing the least significant bits of selected coefficients

SCOPE Background The objective of the EE1003 project is to understand basic concepts in signal processing and transmission by implementing a one-way voice communication system. In this project‚ audio digital signal is transmitted from the transmitter side to the receiver side via a laser link. Subsequently‚ the received signals will be played back using a speaker. The system is illustrated in Figure 1. Figure 1 Project illustration Firstly‚ the project requires to encode the input analog
