Frequency domain automotive sensors: Resolution improvement by novel principle of rational approximation
Fabian Natanael Murrieta-Rico, Oleg Sergiyenko, Vera V. Tyrsa, Daniel Hernandez B., Wilmar Hernández · 2010
It is described a different way to make a frequency counting process that helps to improve fast resolution of an output parameter of a typical automotive frequency domain sensor. After a brief explanation about FDS, specifically SAW sensors work, it is explained a Principle of rational approximation and it is shown its application for fast registration of frequency changes on the adjustable reference oscillator. Some experimental testing is introduced.
