Due to limited resources on a microcontroller and necessarily higher update rates, new concepts for saving time and keeping the measurement precision as constant as possible are compared to each other and trade-offs are given. This paper concludes with an approach that reduces the number of entries of the previously used look-up table (LUT) by 95 % and thus promises to increase the update rate enormously.enfrequency measurement systeminstantaneous frequency measurementsensorsSurface acoustic wavesConference Paper10.1109/WiSNet53095.2022.9721367Other
