and said authorities were verifying the report.
Both devices support Standard 100 kilohertz
(kHz), Fast 400 kHz, and Fast-Plus 1 megahertz (MHz) serial I2C protocols.
Most Class D amplifiers employ pulse width modulation (PWM), typically operating at a switching rate of hundreds of kilohertz
to achieve the required system performance.
heidelbergensis escuchaban especialmente bien en las frecuencias comprendidas entre los 2 y los 4 kilohertz
, justo en las que se transmite el lenguaje hablado.
Depending on the desired direction of motion, the left or right electrode of the piezoceramic plate is excited to produce high-frequency oscillations of hundreds of kilohertz
According to the WHO, electric and magnetic fields in the frequency up to 100 kilohertz
can affect the nervous systems of people exposed at high levels, resulting in acute health effects such as nerve stimulation.
The Mosquito emits a whining sound at 18 kilohertz
that switches on and off four times a second for up to 20 minutes.
A cat can hear ultrasonic frequencies to about 60 to 65 kilohertz
Using equipment designed to study the very high-pitched bleeps that bats make, scientists have found that the frog calls also include very high-pitched chirps that topped 20 kilohertz
(20,000 cycles per second)--sound frequencies that people can't hear.
His lyrical, informal prose is accompanied by scientific diagrams of pitches and notes--musical transcriptions written in kilohertz
rather than eighth notes.
The AM radio frequency ranges from 540 to 1600 kilohertz
, but the band extends far beyond those parameters.
Under the new advice they will now cover all the frequency ranges up to 300 kilohertz
produced by TV and radio transmissions,mobile telecommunications and the supply and use of electricity.
A maximum oscillator frequency up to 500 kilohertz
(kHz) allows the designer to benefit from smaller size magnetic components.
All H8/38004 MCUs provide an on-chip LCD controller, asynchronous event counter, 8-bit timer, 16-bit timer, 2-channel 10-bit pulse width modulation (PWM) timer, watchdog timer, 4-channel 10-bit A/D converter, serial communication interface, clock oscillator, 32 kilohertz
(KHz) sub-clock oscillator and interrupt controller.
Both models are designed to operate in a low-frequency range of 5 hertz to 32 kilohertz
