What does carrier frequency mean in genetics?
Listen to pronunciation. (KAYR-ee-er FREE-kwen-see) The proportion of individuals in a population who have a single copy of a specific recessive genetic variant. Carrier frequency also sometimes refers to the prevalence of variants in dominantly acting genes, such as BRCA1 and BRCA2.
What is the purpose of using carrier frequency?
The purpose of the carrier is usually either to transmit the information through space as an electromagnetic wave (as in radio communication), or to allow several carriers at different frequencies to share a common physical transmission medium by frequency division multiplexing (as in a cable television system).
What is the difference between a frequency and a carrier frequency?
The carrier frequency is the frequency of the carrier, or the suppressed carrier of a signal. For many, perhaps most radio signals, the carrier frequency and the assigned frequency are identical. They are identical for AM (dual sideband) signals. They are different for single sideband radios.
What is carrier frequency value?
Optical fiber communication systems use carrier frequencies in the near-infrared region of the electromagnetic spectrum. The typical value of the optical carrier frequency ν is 193 THz for a wavelength in the 1550-nm range.
How do you calculate carrier frequency in genetics?
The carrier frequency can then be calculated as 2X99/100×1/100 which approximates to 1 in 50. Thus a rough approximation of the carrier frequency can be obtained by doubling the square root of the disease incidence. For an X-linked disorder the frequency of affected males equals the frequency of the mutant allele, q.
What is carrier frequency in VFD?
VFD switching frequency (carrier frequency) refers to the rate at which the DC bus voltage is switched on and off during the pulse width modulation process. In the vast majority of VFDs switching frequency might be changed, typically in the range from 2-16kHz.
What is carrier frequency NMR?
To excite a given nucleus in an NMR experiment, the frequency of the excitation pulse should closely match the resonance frequency of the nucleus. This frequency is referred to as the carrier frequency as it effectively carries the excitation to the nucleus.
What is Carrier Frequency Hardy Weinberg?
Finally according to Hardy Weinberg Equilibrium, the frequency of the heterozygous genotype (a carrier in this case ) is 2pq. This carrier frequency is 2 x 1/50 x 1 = 1/25.
Why carrier signal is used in modulation?
The carrier is higher in frequency than the modulation signal. The purpose of modulation is to impress the information on the carrier wave, which is used to carry the information to another location. In radio communication the modulated carrier is transmitted through space as a radio wave to a radio receiver.
What do you understand by the term carrier wave?
carrier wave, in electronics, the unmodulated single-frequency electromagnetic wave that carries the desired information—i.e., is modulated by the information.
Why is carrier frequency high?
A carrier wave is an electromagnetic wave that is modulated in amplitude or frequency to carry a signal. We need the carrier waves of high frequency for distant communication because high frequency carrier waves travel with the speed of light and do not require a material medium to propagate.
Which frequencies does a carrier use?
Bands that carriers use are numbered and may be assigned to one exclusive carrier, or shared by many carriers. The 700 MHz cell phone frequency range is comprised of multiple bands (12, 13, 17, etc.) and is used in the United States and Canada, and all other ranges are similarly comprised of multiple bands.
What is carrier FREQ in VFD?
VFD switching frequency (carrier frequency) refers to the rate at which the DC bus voltage is switched on and off during the pulse width modulation process. In the vast majority of VFDs switching frequency might be changed, typically in the range from 2-16kHz.
What is meant by a carrier wave?
carrier wave. n. (Electronics) a wave of fixed amplitude and frequency that is modulated in amplitude, frequency, or phase in order to carry a signal in radio transmission, etc.
What is the purpose of a carrier wave?
In telecommunications, a carrier wave, carrier signal, or just carrier, is a waveform (usually sinusoidal) that is modulated (modified) with an input signal for the purpose of conveying information.
