- Abstract:
- New duty-cycle–to–code conversion method is described in the Paper. It is based on the determination of average pulse width and average period during the conversion time Tq. The last one is determined by the beforehand given quantization error δ and equals to the integer number of periods. Due to this, the component error by reason of non-multiplicity of conversion time Tq and period Tx is eliminated. The method allows to measure the duty-cycle in a wide range of frequencies of input signals. The quantization error does not depend on the frequency of converted signal fx and is determined basically by the pulse width τx. The proposed method can be used in different duty-cycle output smart sensors and transducers, as well as in DAQ boards for frequency-time parameters of electric signals.
