Low-Frequency Differentiators and Integrators for
Biomedical and Seismic Signals
Mohamad Adnan Al-Alaoui
Abstract--A general active-network synthesis approach to inverse
system design is introduced. The approach is applied to a passive RC
differentiator and a passive RC integrator to obtain, respectively, a very
low-frequency differential integrator and a very low-frequency differential
differentiator. The frequency ranges of the proposed circuits, from dc to
a few hundred hertz, are particularly suitable to the frequency ranges of
biomedical and seismic signals. The advantages of the proposed circuits
are delineated and include single time constants, dc stable integrators, and
resistive input differentiators. Noninverting and inverting differentiators
and integrators could be obtained by grounding one of the input terminals
in the differential configurations.
Index Terms--Active-network synthesis, biomedical signals, differentia-
tors, integrators, inverse system design, low frequency, seismic signals.
