Purpose. Improving the efficiency of the system by increasing the accuracy in determining the drilling objects spatial orientation, as well as adjusting the system components to more accurately isolate the information signal from the angle transducer. Methodology. A comprehensive increase in the angle transducer accuracy is based on taking into account the influence of factors and errors in determining the drilling objects spatial orientation, as well as a possibility of smoothly tuning the characteristics of the receiving part due to the departure of the information modulated signal frequency from the angle transducer. Findings. Given the converters operating condition, the error in measuring the zenith angle (deviation angle from the vertical) does not exceed 0.3, the installation angle of the deflector is 3. In addition, restructuring the frequency-dependent components characteristics of the systems receiving part allows one to make changes quickly and improve the overall system. Originality. A comprehensive solution to the problem of increasing the control system efficiency is to increase the converter characteristics, by taking into account its errors and operating conditions, as well as increasing the smoothness and tuning the characteristics efficiency of the receiving part, due to the possibility of calculating the transfer function coefficients using simplified ratios, which will greatly simplify the process of processing information and improve the quality of inclinometric work. Practical value. This complex solution is brought to the design, manufacture and experimental converter verification, and algorithms and programs for tuning frequency-dependent components are proposed and brought to implementation.

“…Reconfigurable filters with a broad bandwidth tuning range are realized in [7] and [8] using signal interference technique and multi-resonator cascaded arrangement, respectively. In [9], [10], and [11], bandpass-to-bandstop reconfigurable filters with a fixed bandwidth are achieved by switching signal transmission path (Pin diode) and tuning the resonant frequency of the resonators (varactor diode).…”

A varactor-based fully reconfigurable microstrip bandpass-to-bandpass-with-embedded-stopband filter is presented in this paper. This filter offers wide center frequency and bandwidth tuning flexibility under both bandpass mode and bandpass-with-embedded-stopband mode. The entire tuning ability is based on multiple mode resonator theory and external quality factor tuning structure for bandpass mode and the introduction of transmission zeros (TZs) for bandpass-with-embedded-stopband mode. Under the bandpass mode, the center frequency tuning range is 0.96–1.45 GHz and the bandwidth can be tuned from 0.09 to 1.41 GHz with a fixed center frequency at 1.22 GHz. Under bandpass-with-embedded-stopband mode, the center frequency and bandwidth can be tuned from 0.94 to 1.61 GHz and 0.2–0.33 GHz, respectively. Good agreements are shown between simulated and measured results.
