Wave Frequency: The number of cycle of waves that passes a point in one second. Frequency is measure in hertz (hz). Wave frequency is inversely proportional to wavelength.

Frequency Analyzer: A device that measures the flex, or frequency, of a golf club's shaft by holding the grip end of the club fast while the club head end is bounced, or vibrated, and the cycles per minute (cpm) counted

Frequency Matched: Different club shafts that are of consistent flex as measured by a frequency analyzer

Upstream frequency: The frequency used to transmit data from the CM to the CMTS. Normally in the 5-42 MHz range for US systems and 5-65 MHz for European systems.

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

Downstream Frequency: Refers to the frequency that is used when transmitting information between the CMTS and cable modem.

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).

Frequency Response: The range of frequencies that a speaker will reproduce (lowest frequency to the highest). While the optimal normal is 20 - 20,000 Hz (Hertz), the range of human hearing for individuals is of . . . View Full Definition

Frequency Modulated Continuous Wave Radar (FM CW Radar): Frequency modulated continuous wave radar makes use of frequency modulation to allow the range of a target to be measured.
