Elektronik devrelerin gerçek zamanlı bode diyagramlarının LabVIEW ile elde edilmesi

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.

Obtaining real-time Bode (analysis) of electronic circuits with LabVIEW

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.
