2. Effective radiated power - Wikipedia

   en.wikipedia.org/wiki/Effective_radiated_power

   Effective radiated power ( ERP ), synonymous with equivalent radiated power, is an IEEE standardized definition of directional radio frequency (RF) power, such as that emitted by a radio transmitter. It is the total power in watts that would have to be radiated by a half-wave dipole antenna to give the same radiation intensity (signal strength ...

3. Effective rate of protection - Wikipedia

   en.wikipedia.org/wiki/Effective_rate_of_protection

   Effective rate of protection. In economics, the effective rate of protection ( ERP) is a measure of the total effect of the entire tariff structure on the value added per unit of output in each industry, when both intermediate and final goods are imported. This statistic is used by economists to measure the real amount of protection afforded to ...

4. Event-related potential - Wikipedia

   en.wikipedia.org/wiki/Event-related_potential

   The ERP is plotted with negative voltages upward, a common, but not universal, practice in ERP research. An event-related potential ( ERP) is the measured brain response that is the direct result of a specific sensory, cognitive, or motor event. [ 1] More formally, it is any stereotyped electrophysiological response to a stimulus.

5. Transmitter power output - Wikipedia

   en.wikipedia.org/wiki/Transmitter_power_output

   Transmitter power output. In radio transmission, transmitter power output ( TPO) is the actual amount of power (in watts) of radio frequency (RF) energy that a transmitter produces at its output. [ 1] TPO is a concept related to effective radiated power (ERP), but refers to the power output of a transmitter, without accounting for antenna gain.

6. Material requirements planning - Wikipedia

   en.wikipedia.org/wiki/Material_requirements_planning

   Material requirements planning. Material requirements planning ( MRP) is a production planning, scheduling, and inventory control system used to manage manufacturing processes. Most MRP systems are software -based, but it is possible to conduct MRP by hand as well. An MRP system is intended to simultaneously meet three objectives:

7. Electronic Road Pricing - Wikipedia

   en.wikipedia.org/wiki/Electronic_Road_Pricing

   The Electronic Road Pricing ( ERP) system is an electronic toll collection scheme adopted in Singapore to manage traffic by way of road pricing, and as a usage-based taxation mechanism to complement the purchase-based Certificate of Entitlement system. There are a total of 93 ERP gantries being built and located throughout the country, along ...
