Parasitic CapacitanceAn unavoidable and usually unwanted capacitance that exists between the parts of an electronic component or circuit simply because of their proximity to each other.
Partial Inductancea concept to understand which portions of the loop have the largest impact on loop inductance
Partial Mutual Inductancethe net flux from one segment that passes through a second segment's infinite rectangular loop divided by the current in the first segment
Phase ModulationA modulation pattern that encodes information as variations in the instantaneous phase of a carrier wave.
PhototransistorAn electronic switching and current amplifying device (transistor) that cconverts light energy into electric energy.
Pre-Emphasisa system process designed to increase the magnitude of some frequencies with respect to the magnitude of other frequencies in order to improve the overall signal-to-noise ratio by minimizing the adverse effects of such phenomena as attenuation distortion or saturation of recording media in(...)
ProbeA physical device used to connect electronic test equipment to the device under test.
Push-Pull OutputA type of electronic circuit that uses a pair of active devices that alternately supply current to, or absorb current from, a connected load.
Quadrature amplitude modulationA modulation method of using both an (in-phase) carrier wave and a 'quadrature' carrier wave that is 90° out of phase with the main, or in-phase, carrier.
QAMA modulation method of using both an (in-phase) carrier wave and a 'quadrature' carrier wave that is 90° out of phase with the main, or in-phase, carrier.
Radiated EmissionsThe unintentional release of electromagnetic energy from an electronic device or apparatus.
Radiated ImmunityAbility to withstand electromagnetic energy that arrives via free-space propagation.
Radiated SusceptibilityThe determination or measurement of a device's capability to function in the presence of undesirable radiated EMI from external electromagnetic sources.
Radio Equipment DirectiveThe Radio Equipment Directive (RED) (2014/53/EU) ensures a Single Market for radio equipment by setting essential requirements for safety and health, electromagnetic compatibility, and the efficient use of the radio spectrum. It applies to all products using the radio frequency spectrum and(...)
