On the selection of excitation signals for the fast spectroscopy of electrical bioimpedance
Journal of Electrical Bioimpedance, 2018 Different excitation signals are applicable in the wideband impedance spectroscopy in general. However, in electrical bioimpedance (EBI) measurements, there are limitations that set specific demands on the properties of the excitation signals. This paper

Mixing efficiency in heterodyne systems [PDF]
How the spatial distributions of the signal and local oscillator fields affect the heterodyne signal to noise ratio is examined for both a single detector and an array of detectors. For an array, the distribution of gain among the intermediate frequency (

Characterisation of the signal to noise ratio of 2-photon microscopes
Scientific ReportsThe signal to noise ratio (SNR) is a key performance metric of an imaging instrument. Here we describe the characterisation of SNR of a custom 2-photon microscope and compare the SNR performance of our microscope with selected commercial 2-photon ...

Symbol signal-to-noise ratio loss in square-wave subcarrier downconversion [PDF]
This article presents the simulated results of the signal-to-noise ratio (SNR) loss in the process of a square-wave subcarrier down conversion. In a previous article, the SNR degradation was evaluated at the output of the down converter based on the ...
