C++ From Scratch: An Object-Oriented Approach is designed to walk novice programmers through the analysis, design and implementation of a functioning object-oriented application using C++. You will learn all the critical programming concepts and techniques associated with the language in the context of creating a functioning application. Best selling C++ author Jesse Liberty shows you how to create "Decryptix", a game of decoding a hidden pattern as quickly as possible, using nothing but successive guesses and the application of logic. Every example and technique is put into the context of achieving a goal and accomplishing an end.

INTRODUCTION In the past, adding speech recording and playback capability to a product meant using a digital signal processor or a specialized audio chip. Now, using a simplified Adaptive Differential Pulse Code Modulation(ADPCM) algorithm, these audio capabilities can be added to any PICmicro device. This application note will cover the ADPCM compression and decompression algorithms, performance comparison of all PICmicro devices, and an application using a PIC16C72 micro-controller.DEFINITION OF TERMS step size -value of the step used for quantization of ana-log signals and inverse quantization of a number of steps.quantization -the digital form of an analog input signal is represented by a finite number of steps.adaptive quantization -the step size of a quantizer is dramatically changed with time in order to adapt to a changing input signal.inverse quantizer -a finite number of steps is converted into a digital representation of an analog signal.
