Frequency Modulation (FM)

Technology / Home Audio / Frequency Modulation (FM): In radio broadcasting, a method of modulation in which the frequency of the carrier voltage is varied with the frequency of the modulation voltage (Also see Amplitude Modulation).

Quadrature Amplitude Modulation (QAM)

Technology / Computers / Quadrature Amplitude Modulation (QAM): A method of modulating digital signals using both amplitude and phase coding. Used for downstream and can be used for upstream. MORE

Pulse Width Modulation (PWM)

Technology / Programming / Pulse Width Modulation (PWM): Is a way of simulating an analog output by varying high and low signals at intervals proportional to the value. MORE

Radio Frequency (RF)

Technology / Cell Phones / Radio Frequency (RF): The spectrum of electromagnetic energy between audio and light: 500 KHz to 300 GHz. MORE

Radio Frequency Identification (RFID)

Technology / Computers / Radio Frequency Identification (RFID): RFID first appeared in tracking and access applications during the 1980s. It is a method of remotely storing and retrieving data using devices called RFID tags/transponders and is coming into increasi MORE

Radio Frequency Interference (RFI)

Technology / Computers / Radio Frequency Interference (RFI): A high-frequency signal radiated by improperly shielded conductors. RFI can interfere with the operation of other electronic devices. MORE

Pulse Repetition Frequency (PRF)

Technology / Radar / Pulse Repetition Frequency (PRF): The number of radar pulses transmitted each second. The pulse transmission rate is automatically lengthened for longer ranges. MORE
