Abstract

Bode diagram is a term used in
many fields of science and engineering that can be described as frequency
response analysis. LabVIEW is a multifunctional program for acquiring,
processing and analyzing data. In this paper, real time Bode diagram of
electronic circuits are obtained in LabVIEW platform without using special
VIs(virtual instruments) such as SI Bode Plot VI. In addition to this, the
realized study can be easily integrated in to other commonly used platforms
such as MATLAB and C to obtain bode diagram results in real time. To evaluate
performance of the realized study, Bode diagram results obtained from LabVIEW
is compared with the results obtained from ORCAD-PSpice simulations.

Elektronik devrelerin gerçek zamanlı bode diyagramlarının LabVIEW ile elde edilmesi

Abstract

Bode diyagramı, bilim ve mühendisliğin birçok alanında
kullanılan, kısaca frekans cevabı analizi olarak tanımlanan bir kavramdır. LabVIEW;
verilerin toplanması, işlenmesi ve analizlerinin yapılabilmesi için çok uygun
ve işlevli bir programdır. Bu çalışmada, SI Bode Plot VI gibi özel VI'lar
(sanal enstrümanlar) kullanılmadan, elektronik devrelerin gerçek zamanlı bode
diyagramlarının LabVIEW programı ile elde edilmesine yönelik farklı bir çalışma
gerçekleştirilmiştir. Ayrıca, gerçekleştirilen çalışma, çok sık kullanılan
MATLAB veya C gibi diğer platformlara da kolaylıkla entegre edilerek, gerçek
zamanlı bode diyagram sonuçları alınabilir. LabVIEW’de elde edilen bode
diyagram sonuçları, ORCAD-PSpice benzetim sonuçları ile karşılaştırılarak,
yapılan çalışmanın başarımı gösterilmiştir.
