Product data management (PDM) is the name of a business function within product lifecycle management (PLM) that denotes the management and publication of product data. [1] In software engineering, this is known as version control. The goals of product data management include ensuring all stakeholders share a common understanding, that confusion ...
Pulse-density modulation, or PDM, is a form of modulation used to represent an analog signal with a binary signal.In a PDM signal, specific amplitude values are not encoded into codewords of pulses of different weight as they would be in pulse-code modulation (PCM); rather, the relative density of the pulses corresponds to the analog signal's amplitude.
PDM (cycling team), the cycling team sponsored by Philips Dupont Magnetics; PDM Group of Institutions (popularly known as PDM) is a Group of Educational Institutions located in India; Penny-drop moment, an abbreviation used by cryptic crossword bloggers; Philips Dupont Magnetics, a joint venture between Philips and DuPont
Pulse-width modulation (PWM), also known as pulse-duration modulation (PDM) or pulse-length modulation (PLM), [1] is any method of representing a signal as a rectangular wave with a varying duty cycle (and for some methods also a varying period). PWM is useful for controlling the average power or amplitude delivered by an electrical signal.
Polarization-division multiplexing (PDM) is a physical layer method for multiplexing signals carried on electromagnetic waves, allowing two channels of information to be transmitted on the same carrier frequency by using waves of two orthogonal polarization states.
The precedence diagram method (PDM) is a tool for scheduling activities in a project plan. It is a method of constructing a project schedule network diagram that uses boxes, referred to as nodes, to represent activities and connects them with arrows that show the dependencies. It is also called the activity-on-node (AON) method.
Public Domain Mark (PDM) is a symbol used to indicate that a work is free of known copyright restrictions and therefore in the public domain. It is analogous to the copyright symbol , which is commonly used to indicate that a work is copyrighted, often as part of a copyright notice .
The concept of product management originates from a 1931 memo by Procter & Gamble President Neil H. McElroy.McElroy, requesting additional employees focused on brand management, needed "Brand Men" who would take on the role of managing products, packaging, positioning, distribution, and sales performance.
