Heart rate variability:
The term time domain is used to portray the study of mathematical functions, or real-life signals, with respect to time. In the time-domain, the indication or function's value is known at different discrete time points; or for all real numbers, for the case of uninterrupted time period. A general frequency domain system is the application of the discrete Fourier transform to the beat-to-beat time period time series. That demonstrates the quantity of variation for diverse frequencies. Numerous frequency bands of attention have been defined in humans.
High Frequency band is determined by respiration and appears to derive mainly from vagal movement. Low Frequency band derives from both vagal and sympathetic action and has been hypothesized to replicate the impediment in the bar receptor loop. Very Low Frequency band (VLF) band is found in between 0.0033 and 0.04 Hz. The origin of this band is unknown, but it had been credited to corporeal activity. Ultra Low Frequency (ULF) band can be established between 0 and 0.0033 Hz. The major background of this band is day/night variation.A system that is biological which functions in the frequency domain is the auditory system, in which the basilar membrane of the inner ear is able to operate a power spectrum decomposition of incoming sound waves. The consequence is that we are able to hear a divesrse range of different frequencies played together as a collection of separate notes, rather than simply a complicated noise.
