Amplitude, phases and, frequencies of the signal components are assumed unknown, as well as the threshold level of the comparator used to produce measurement results. To provide enough information at the one-bit quantizer input, a sinewave is assumed to dither one of the two comparator’s inputs. To ease the procedure's application, only the peak-to-peak amplitude of this dither signal is assumed known.

A comparison between different types of sequences applied at the input of Wiener systems is provided by numerical simulations. The performance of the sequences is compared with a white Gaussian noise signal for reference purposes. It is shown that the randomized constrained approach for designing ternary sequences has a low sensitivity to even and odd order nonlinearity, resulting in a response close to the actual response of the underlying linear system.

The proposed wearable tracking unit is placed on the finger and it is wirelessly powered without using cables or batteries, thus enhancing freedom of movement. The system is comprised by two sections: a measurement unit and a wireless power transfer apparatus. The measurement unit consists of an electronic board able to measure, acquire and transmit sensors signals; a stretch sensor and an inertial measurement unit are integrated on the measurement unit. Furthermore, the wireless power transfer apparatus is implemented by means of inductively-coupled resonant circuits. A prototype of the developed system is characterized by experimental tests. Results show the feasibility of the proposed approach. The measuring system can track finger movement with a sample rate of 30 Hz, while the wireless power transfer system demonstrates the capability of transferring 67.72 mW, necessary to power the measurement unit, at a maximum distance of about 8 cm.

Two types of binary sequences are considered, i.e. sigma-delta modulated multisine sequences and maximum-length binary sequences. Their performance is evaluated using a low-complexity experimental setup. Results prove that the two types of sequences are capable of estimating the complex impedance of a battery in the frequency range of interest 1 Hz-200 Hz with an RMSE smaller than 5% with respect to a reference instrument. Both sequences are suitable for implementing online in-situ EIS monitoring, because they enable fast measurement and simple integration within the battery cell itself.

In particular, a low-cost setup comprised of a non-uniform digital-to-analog converter (DAC), an analog filter, and a non-uniform analog-to-digital converter (ADC) is considered. First, the effect of DAC nonlinearity on the spectrum of randomized constrained sequences (RCS) is described and validated. Then, based on this effect, a method for generating RCS signals with high spectral purity is proposed. The feasibility of this method is evaluated by numerical simulations and experimental tests.
