This paper presents the design and evaluation of the hardware circuit for electronic stethoscopes with heart sound cancellation capabilities using field programmable gate arrays (FPGAs). The adaptive line enhancer (ALE) was adopted as the filtering methodology to reduce heart sound attributes from the breath sounds obtained via the electronic stethoscope(More)
In this paper, we investigate the aspects of constructing an electronic stethoscope with the capability to filter out heart sound from the lung sound pickups in real time. Such a capability is most useful for the clinical diagnosis of pulmonary diseases. The proposed filter design is based on the adaptive line enhancer (ALE) filter structure to be(More)
This article presents a practical realization of a recently basic building block for analog signal processing, namely current control current feedback amplifier (CC-CFA) using the commercially available ICs. It can be realized by the commercially available ICs, AD844 to perform as a current conveyor and LM13600N to function as a floating resistance(More)
