Utilization of Digital Potentiometers in ARC Filter Re-tuning
Original language description
In spite of the current dominance of digital technology, analog filters have retained their importance for applications such as data preprocessing in electronic systems. Within the field, various methods of connecting universal and easily retunable ARC filters are used to provide the best attainable form of the parameters required for signal processing circuits; the group of these parameters includes, for example, the separation of effective signals from noise. The aim of this work is to explore and verify different utilization possibilities related to modern digital potentiometers that could enable us to realize a comparatively simple connection of the tunable block of an active filter. Such a filter is applicable within a broad frequency range and can be used universally in the circuits of analog data preprocessing systems. Even though these circuits were originally designed for application in acoustic devices, they appear to be a promising solution for the realization of tuning in u
