Frequency

Technology / Television (TV) / Frequency: The number of times per second that a signal fluctuates. The international unit for frequency is the hertz (Hz). One thousand hertz equals 1 khz (kilohertz). One million hertz equals 1 mhz (megahertz). One billion hertz equals 1 ghz (gigahertz). Television is broadcast in frequencies ranging from 54 mhz to 216 mhz (VHF) and 470 mhz to 806 mhz (UHF)

Frequency Modulated Continuous Wave Radar (FM CW Radar)

Technology / Radar / 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. MORE

Wave Frequency

Technology / Radar / 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. MORE

Cutoff Frequency Filters

Technology / Home Audio / Cutoff Frequency Filters: The frequency at which a signal falls off by 3 db (the half power point) from it's maximum value. Also referred to as the -3 db points, or the corner frequencies MORE
