Abstract— We propose a simple speech compression algorithm using subband division and ADPCM (Adaptive Differential Pulse Code Modulation) algorithm. Although speech data are stored in a semiconductor memory device, its capacity and the available network capacity are limited. Therefore, it is necessary to compress the data as much as possible. The first is that the reconstructed datum must be understood correctly. Speech signal is compressed with a ratio of 1/4 using the proposed subband division and ADPCM (Adaptive Differential Pulse Code Modulation) algorithm.

This document will describe some of the general usage of MATLAB s Data Acquisition Toolbox (DAT). The software in the toolbox allows MATLAB to acquire data from sensors and to send out electrical signals that can be used to control or drive external devices. We will be using this toolbox with two different pieces of hardware. One is the sound card built into your laptop, the microphone and speaker will serve as the data acquisition (and output) devices. The sound card provides convenience because it will allow you to test the DAT outside of the lab. We will also be using Measurement Computing data acquisition cards that will ¯ t into your laptops PCMCIA slot, these devices will be in the class laboratory. The data acquisition (DAQ) cards allow your computer to acquire data from many different types of sensors.
