16-BITPRO SOUND January 18, ANTEX ELECTRONICS CORPORATIONSX-3 SX-33 SX-33b SX-33e 16100 SOUTH FIGUEROA STREET GARDENA, CALIFORNIATABLE OF CONTENTS FIGURES INTRODUCTION ABOUT DIGITAL AUDIOIn essence, digital audio is a technological process whereby an analog audio signal produced when sound waves in the air excite a microphone is first converted into a continuous stream of num- bers or digits. Once in digital form, the signal is extremely im- mune to degradation caused by system noise or defects in the storage or transmission medium unlike previous analog sys- tems. The digitized audio signal is easily recorded onto a variety of optical or magnetic media, where it can be stored indefinitely without loss. The digitized signal is then reconverted to an analog signal by reversing the digitizing process. In digital audio rec- ord/playback systems, each of these two functions is performed separately. In digital audio signal processing systems where no record/playback function occurs both analog-to-digitaland digital- to-analogconversion processes occur simultaneously. A variety of techniques are possible, but the most common method by which audio signals are processed digitally is known as linear pulse code modulation, or PCM. Lets take a brief look at how PCM works Figure 1. Analog-to-DigitalConversion Page Figure 2. Digital-to-AnalogConversion MINIMUM HARDWARE RECOMMENDED ADAPTER INSTALLATIONJUMPER SETTINGS Figure 3.
