Radio frequency (RF) is a measurement representing the oscillation rate of electromagnetic radiation spectrum, or electromagnetic radio waves, from frequencies ranging from 300 gigahertz (GHz) to as low as 9 kilohertz (kHz). With the use of antennas and transmitters, an RF field can be used for...
The molecular target of the acaricide amitraz is considered to be the octopamine receptor (OAR). Changes in the OAR sequence gene could be responsible of the cattle ticks becoming resistant to amitraz. A putative octopamine receptor was cloned and sequenced from a susceptible and an amitraz ...
what is a kilohertz (khz)? learn more what is a kilohertz (khz)? khz is a unit of frequency equal to 1,000 cycles per second. it is commonly used to measure frequencies in various fields, including technology, computing, programming, and communications. how does kilohertz relate to sound?
Before we start discussing FM modulation we take a look at some important terms. Modulation: The process by virtue of which some characteristic, normally amplitutude, frequency, phase of a voltage signal is varied in accordance to the instantaneous value of some other voltage signal called “Carr...
Radio frequency (RF) refers to the rate of oscillation of electromagnetic radio waves in the range of 3 kHz to 300 GHz, as well as the alternating currents carrying the radio signals. This is the frequency band that is used for communications transmission and broadcasting. Although RF really ...
Frequency modulation (FM) synthesis is a popular technique used for generating rich sound palettes in the process of sound synthesis. Initially implemented in analog systems, FM synthesizers are now implemented digitally. FM synthesizers using analog oscillators suffer from pitch instability; as a result...
What is frequency-division multiplexing (FDM)? In frequency-division multiplexing (FDM), multiplesignalsare combined for transmission on a single communications line orchannel, with each signal assigned to a different frequency (subchannel) within the main channel. ...
That’s FM synthesis at work, and the possibilities are pretty much endless from there. Depending on the synth, you can adjust the amount of modulator and carrier waves, as well as how they connect to one another. The frequency ratio of a modulator wave to its carrier wave is also really...
What is a sound wave? Given the speed of sound is 331 m/s in air, and a sound wavelength of 7.11 m, what is the frequency of the sound in Hz? If the period of the lowest-frequency sound you can hear is 0.050 s, then what is its frequency?
Frequency is one of the characteristics of waves such that it describes the number of cycles of waves per second. This, therefore, can be related to the wavelength of the wave, such that λ=vf, where v is the velocity of the wave and f is the frequency....
