kHz : kHz is an abbreviation for kiloHertz. The term Hertz, named for the inventor, refers to the number of times an electrical signal of alternating current "crosses" the "0" line and changes from positive to negative and back to positive. Human hearing is nominally in the 50 to 15,000 Hertz range. A kiloHertz is 1000 Hertz (15,000 Hertz = 15 kHz). Frequencies above about 100 kHz are said to be in the "Radio Frequency Range" as they are used for transmitting sonic or digital information.
