Abstract

Signal generators play a very important role in designing and testing circuits. They can supply various commonly used waveforms and can be designed using analog, digital, and Direct Digital Synthesis methods. Some signal generators have very low current output. In this paper, it is shown that a signal generator can be made using a cheap microcontroller board such as the Arduino Nano Klon V3.0 microcontroller. A power opamp TDA2030 is used to increase its output current. The signal generator can be operated up to 500 Hz Also, the signal generator can give an output current of up to 3 Amperes. The signal generator can be programmed to supply various common waveforms as well as any desired waveform considering its frequency limit.

YÜKSEK ÇIKIŞ AKIMINA SAHİP MİKRODENETLEYİCİ TABANLI SİNYAL JENERATÖRÜ

Abstract

Sinyal üreteçleri devrelerin tasarımında ve test edilmesinde çok önemli bir rol oynamaktadır. Onlar yaygın olarak kullanılan çeşitli dalga formlarını sağlayabilirler ve analog, sayısal ve doğrudan sayısal sentezleme yöntemleri ile tasarlanabilirler. Bazı sinyal üreteçleri çok düşük akım çıkışına sahiptir. Bu makalede, Arduino Nano Klon V3.0 mikrodenetleyici gibi ucuz bir mikrodenetleyici kartı kullanılarak bir sinyal üretecinin yapılabileceği gösterilmiştir. Çıkış akımını artırmak için bir güç opampı olan TDA2030 kullanılmıştır.. Sinyal üreteci 500 Hz’e kadar çalıştırılabilmektedir. Ayrıca, sinyal üreteci 3 Ampere kadar çıkış akımı verebilmektedir. Sinyal üreteci, frekans limiti göz önünde bulundurularak çeşitli yaygın dalga biçimlerinin yanı sıra istenen herhangi bir dalga şeklini sağlamak üzere programlanabilir.
