RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling
2 MB. Its primary purpose was to provide me with ready access to commonly needed
formulas and reference material while performing my work as an RF system and circuit
design engineer. The World Wide Web (Internet) was largely an unknown entity at
the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps
while tying up your telephone line, and a nice lady's voice announced "You've Got
Mail" when a new message arrived...

Ultrasonic Frequency Spectrum |
Ultrasound is cyclic sound pressure with a frequency greater than the upper limit of human hearing. Although this
limit varies from person to person, it is approximately 20 kilohertz (20,000 hertz) in healthy, young adults and
thus, 20 kHz serves as a useful lower limit in describing ultrasound. The production of ultrasound is used in many
different fields, typically to penetrate a medium and measure the reflection signature or supply focused energy.
The reflection signature can reveal details about the inner structure of the medium. The most well known
application of this technique is its use in sonography to produce pictures of fetuses in the human womb. There are
a vast number of other applications as well. - Wikipedia
