Parameters Method of parameter calculation Note length Measured as the difference between begin time and end time for the call selection Centre frequency
Calculated by dividing the call selection into two frequency intervals of equal energy.
The incident mode is a 10-cycle Hanning-windowed toneburst with a centre frequency
It will have two types of signals in L5 and S-band centre frequency
, with the L band centre frequency
Regulate the circumscribed resistance R3 of chip pin 5, setting the centre frequency
of filter on 40 kHz achieve good result.
The new technology allows a frequency span of up to 46% above the centre frequency
, rather than less than 20% in previous combiners.
This parameter is Q and defined as the bandwidth of a filter divided by its centre frequency
These probes use ultrasound at centre frequency
of 20MHz and are designed to image the ~10mm of soft tissue that is normally found over the bony prominences of the most comment pressure ulcer sites.
