Abstract

This paper
presents memristor based filter implementation for biomedical signal. For this
purpose, memristor based high-pass and low-pass filter circuits are constructed
by simply replacing resistor with memristor emulator circuit in well-known R-C
filter structures. The filter circuits are constituted on board and firstly
sine wave is applied as input signal. Then, Electrocardiographic (ECG) signal
is applied as input for M-C filter circuits. The results are obtained and
analysed in real-time. In the implementation stage of study, LabVIEW platform
and DAQ card are used to obtain real-time data. The results show that memristor
can be used quite easily to sort out biomedical signal processing applications
and shows better performance.

Memristör Tabanlı Filtre Tasarımı ve ECG Sinyali için Uygulanması

Abstract

Bu çalışma memristör tabanlı filtrenin biyomedikal
sinyal için uygulanmasını göstermektedir. Bu amaçla, sık kullanılan R-C filtre
yapıları ile memristör tabanlı yüksek-geçiren ve alçak-geçiren filtre devreleri
basitçe resistör elemanı yerine memristör taklitçi devresinin
yerleştirilmesiyle oluşturulmaktadır. Filtre devreleri board üzerinde kurularak
ilk önce girişine sinüs işareti uygulanmaktadır. Ardından, Electrokardiyografi
(EKG) sinyali M-C filtrenin girişine uygulanmaktadır. Sonuçlar gerçek zamanlı
elde edilip analiz edilmektedir. Çalışmanın uygulama aşamasında LabVIEW arayüzü
ve DAQ kartı kullanılmaktadır. Filtreleme işlemi sonucunda memristörün
biyomedikal sinyal işleme uygulamalarında kolaylıkla kullanılabileceği
görülmektedir.
