Bat cries are ultrasonic, above the range of human hearing, or about 15 kilohertz
equals 1,000 hertz, or 1,000 cycles per second).
This helps to simplify the massive range of noises made by dolphins, who produce sounds at frequencies up to 200 kilohertz
- roughly 10 times higher than humans can hear.
Supersensitive hearing lets wax moths eavesdrop on bats that squeak out calls at frequencies up to 212 kilohertz
to echolocate prey, the researchers report in the August 23 Biology Letters.
If you want to pick up frequencies of, say, one kilohertz
, you have to sample at least twice per millisecond.
A variety of techniques and solutions may be used to create a clock source, but whether the required frequency is a few kilohertz
or over 100 MHz, designers must consider factors including cost, power consumption, footprint, stability over temperature and supply voltage, and generated noise.
Now, with the original version known as "Teen Buzz" already having hit the US, the company has developed its own 17 kilohertz
version of the ringtone.
, with a cut-off at 3 kilohertz
- the pitch of a human scream.
The control board features a digital oscillator for accurate velocity control with an output frequency of up to 100 kilohertz
, which will vary with the level of the 0 to +5 VDC input via a 10 kOhm potentiometer.
One of the goals of the new 3D Imaging R&D contract will be to extend this proprietary software to gigahertz (GHz) per pixel processing speed, versus the kilohertz
(KHz) per pixel processing currently available, to support the rapid build-up of 3D images.
02 a 20 kilohertz
, la capacidad de la beluga abarca hasta 120 kilohertz
With full 8 kilohertz
(kHz) bandwidth wideband voice capture for VoIP communication, de-reverberation capability and 360-degree voice pickup, BelaSigna R262 is ideal for conference, handset and arm's length applications.
(kHz) channel spacing in the range of 118 to 137 megahertz (MHz).
