Speech Compression by Using Adaptive Differential Pulse Modulation: Compression is a process of converting an input data stream into another data stream that has a smaller size - Softcover

Inhaltsangabe

Compression is a Technique in which the original signal size is reduced in small size with good quality. Because of the Compression, we save the the memory & whenever we want that data we Decompress. In this book we going to compress the data by using Adaptive Differential Pulse Code Modulation with Microcontroller. Here, we reduce the data upto 4-bits or 5-bits because original data having set in 10-bits. There So many Analog signal are available that take more space of memory. Because of Compression we reduce the original signal in small size with good quality. Adaptive Differential Pulse Code Modulation takes the advantages of difference between the next sample & predicted sample. Because of the sample difference signal voltage goes reduces. In the recent years, large scale information transfer by remote computing and the development of massive storage and retrieval systems have witnessed a tremendous growth. One solution to these problems is-“COMPRESSION” where the database and the transmission sequence can be encoded efficiently.
