Part 5. Advanced and Self-Adapted Conversion Methods

Abstract. The 5th part of this course is devoted to advanced and self-adapted conversion methods and includes description of ratiometric counting method, reciprocal counting method, M/T counting method, constant elapsed time (CET) method single- and double buffered methods, DMA transfer method, method of dependent count (MDC) and method with non-redundant reference frequency. Detailed, comparative analyze for metrological performances (components of resulting error, quantization error, dynamic error,  frequency range and conversion time)  advantages, disadvantages and measures how to reduce the quantization error are given and illustrated by examples. For many of them, time diagrams, example of realization, modeling and experimental results are included. This parts also discusses advanced patented methods for duty-cycle - to - digital and phase shift-to-digital conversion. Two patented methods: the MDC and method with non-redundant reference frequency is very suitable for smart sensors systems creation because of its high metrological characteristics and self-adapted possibilities.
