Maletin, I.V. Fominov, M.A. Khatanzeyskaya, A.I. Klyuchnikov A method is proposed for numerically-analytical calculation of the parameters of a lowpass filter of a pendulum accelerometer operating in the mode of selfoscillations. The damping links of the first and second order of the accelerometer, operating in the mode of selfoscillations, allowing to minimize the noise components of the measurement error and the transition time, are calculated. It is shown that the secondorder filter provides the best performance. Keywords: pendulum accelerometer, self-oscillation mode, low-pass filter, amplitude-phase characteristic, harmonic linearization method. DOI: 10.25791/aviakosmos.11.2020.1187 Pp. 10-19.
