FIELD: physics.
SUBSTANCE: acceleration measurement device has a local positive feedback which includes an aperiodic link, a local negative feedback which includes a second order broadband filter and an integrating negative feedback.
EFFECT: stability of the device and wider bandpass, while the integrating negative feedback covering the entire device increases accuracy owing to first order astatism and owing to formation of a pulsed connection in the return circuit.
