<data> (PCM) A method by which an audio signal is represented as digital data. Virtually all digital audio systems use PCM, including, CD, DAT, F1 format, 1630 format, DASH, DCC, and MD. Many people get confused because "PCM" is also slang for Sony's F1 format which stores PCM digital audio on videotape. (1995-02-09)
Clinical coder         
HEALTH CARE PROFESSIONAL WHOSE MAIN DUTIES ARE TO ANALYSE CLINICAL STATEMENTS AND ASSIGN STANDARD CODES USING A CLASSIFICATION SYSTEM
Medical coder; Medical coding; Clinical coding; Medical coding specialist
A clinical coder—also known as clinical coding officer, diagnostic coder, medical coder, or nosologist—is a health information professional whose main duties are to analyse clinical statements and assign standard codes using a classification system. The Health data produced are an integral part of health information management, and are used by local and national governments, private healthcare organizations and international agencies for various purposes, including medical and health services research, epidemiological studies, health resource allocation, case mix management, public health programming, medical billing, and public education.

Wikipedia

Transform coding

Transform coding is a type of data compression for "natural" data like audio signals or photographic images. The transformation is typically lossless (perfectly reversible) on its own but is used to enable better (more targeted) quantization, which then results in a lower quality copy of the original input (lossy compression).

In transform coding, knowledge of the application is used to choose information to discard, thereby lowering its bandwidth. The remaining information can then be compressed via a variety of methods. When the output is decoded, the result may not be identical to the original input, but is expected to be close enough for the purpose of the application.
