    "abstract": "Bu çalışmada, robotik uygulamalarda yaygın bir şekilde kullanılan kapasitif rotary enkoder anlatılacaktır. Kapasitif rotary enkoderler hem açısal pozisyon hem de açısal hız ölçmede kullanılmaktadır. Enkoder temel olarak 3 ana parçadan oluşmaktadır: 1. komple iletken olan sabit dairesel plaka; 2. merkezi diğer plakalardan kaydırılan yalıtkan hareketli plaka; 3. komple iletken ve elektrotların olduğu dört eşit parçaya ayrılan sabit alt plaka. Bir sinüzoidal sinyal, komple iletken olan sabit plakaya uygulanmaktadır. Dönme hareketi esnasında iki iletken plaka arasında kapasitans oluşmaktadır. Sinüzoidal sinyal,\r\nkapasitans-gerilim entegreleri sayesinde modülasyon işlemine hazırlanmıştır. Ardından, MATLAB ortamında çift yan bant demodülasyon işlemi ile açısal hız ve pozisyon çıktısı elde edilmiştir. MATLAB ortamında; iki iletken plaka arasında kapasitans oluşumu, çift yan bant modülasyon ve demodülasyon işlemi, demodülasyon işleminden geçen sinyale 2. dereceden alçak geçiren filtre uygulanması ve arctangent işlemi gerçekleştirilmiştir. Çalışma sonucunda, girişte gürültülü bir şekilde sisteme uygulanan sinüzoidal sinyalin çıkışta gürültüsüz olduğu gözlenmiştir.  ",

    "english_title": "Dual Sideband Modulation and Demodulation Based Capacitive Rotary Encoder",
    "english_abstract": "In this study, a capacitive rotary encoder, which is used widely in robotic applications, will be described. Capacitive rotary encoders are used for both angular position and angular velocity measurement. The encoder basically consists of three parts: 1. fixed circular plate with complex conductor; 2. moving plate with insulator shifted from other central plates; 3. fixed bottom plate divided into four equal parts with complex conductor and electrodes. A sinusoidal signal is applied to a fixed plate, which is a complex conductor. During the rotation movement, the capacitance is formed between the two conducting plates. The sinusoidal signal is prepared for the modulation process by capacitance-to-voltage integrations. Subsequently, in the MATLAB environment, the angular position and velocity output were obtained by double sideband demodulation. In the MATLAB; capacitance formation between two conductive plates, double sideband modulation and demodulation, application of 2nd low pass filter to the signal passing through demodulation process and arctangent operation are performed. As a result of study, it was observed that the signal applied to the system in a noise condition at the input was noiseless at the output.",
