What is meant by carrier frequency?

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. Also called carrier rate.

What should be the carrier frequency?

In telecommunications, carrier frequency is the frequency (the number of waves per second) of a carrier wave (a wave that carries a signal to convey information). Carrier frequency is measured in Hertz (Hz). For example, a carrier frequency of 10 Hz means that there are 10 carrier waves per second.

How do you choose a sampling frequency in FFT?

The frequency resolution is equal to the sampling frequency divided by FFT size. For example, an FFT of size 256 of a signal sampled at 8000Hz will have a frequency resolution of 31.25Hz. If the signal is a sine wave of 110 Hz, the ideal FFT would show a sharp peak at 110Hz.
