Technology / Home Audio / Frequency: 1. The property or condition of occurring at frequent intervals. 2. Mathematics. Physics. The number of times a specified phenomenon occurs within a specified interval. In sound this simply refgers to the regular occurence of compression and rarification of air that we experience as sound.
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
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
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
Technology / Radar / Digital Radio Frequency Memory (DRFM): Digital radio frequency memory is an approach being adopted by modern electronic attack (ea) systems to combat pulse-compression radar. A digital radio frequency memory system receives radar pulses, s MORE
Technology / Radar / Frequency Diversity: Frequency diversity refers to the use of complementary radar transmissions or multiple radar systems operating cooperatively at different frequencies. MORE
