The BBC Research Department made major contributions to broadcast technology, carrying out original research in many areas, and developing items like the Peak programme meter (PPM) which became the basis for many world standards. A peak programme meter (PPM) is an instrument for indicating the level, loudness or volume of an electronic audio signal. ...
