A SEMINAR ON DIGITAL SIGNAL PROCESSING

Digitals signals are different than analog signals in that digital signals have two discrete states. These states are either “off” or “on”.   The primary objective of data transmission is the transfer of information from one location to another. In contrast to the analog signal that has an infinite number of voltage levels, the digital signal information is “binary” or… Read moreA SEMINAR ON DIGITAL SIGNAL PROCESSING

Multimedia Rich Virtual Classroom Environment Development

Virtual environment is a computer simulated environment not a physical environment but giving a feel of physical like environment. There is considerable development for computer supported learning by way of computer based teaching (CBT) and web based teaching (WBT) and its extension to computer based learning (CBL) and web based learning (WBL). This is supportive e-learning infrastructure. One has to… Read moreMultimedia Rich Virtual Classroom Environment Development

Speech Recognition

Speech is the most natural and common way of communication between people. It would seem only natural that computer development would eventually progress to the point where people would want to extend the human-computer interface to include speech. Once this happened, numerous techniques were explored. In our paper a light is shed on the contemporary field of speech recognition.  … Read moreSpeech Recognition
