Özet
Bu çalışmada, daha önce başka çalışmalarda oluşturulmuş olan frekans uyarlama işlemi ile faz kilitleme işlemi arasındaki ilişki detaylı bir şekilde incelenip, frekans uyarlama kuralının nasıl oluşturulduğu gösterilmiştir. Ayrıca bu senkronizasyon kuralı ilk kez bu tezde kaynak bağlamalı osilatörün denklemine eklenmiştir. Frekans uyarlamalı kaynak bağlamalı bu osilatörün yeni denklemleri, bir sayısal analiz programı yardımıyla çözülmüş ve teorik öngörülerin geçerliliği test edilmiştir. Oluşturulan yeni denklemler daha önce bu kuralla beraber denenmiş olan Hopf osilatörün denklemleri ile benzetimleri yapılarak karşılaştırılmıştır. Uyarlamalı osilatöre ilişkin model denklemlerinden yola çıkılarak, fiziksel devre elemanları ile gerçeklenebilecek frekans uyarlamalı kaynak bağlamalı bir osilatör devresi tasarlanmış ve bu devre PSpice benzetim programı yardımıyla test edilmiştir.
In this study, the realization method of the adaptation rule was shown by examining the relationship between the phase-lock and frequency adaptation process in details which is studied earlier. In addition, the adaptation rule was added to the equations of the source coupled multivibrator which has applied for the first time in this thesis. These new equations are compared with the Hopf Oscillator’s equations which were simulated with this adaptation rule before. The equations of this adaptive frequency source coupled oscillator was solved using a numerical simulation program and the validity of the theoritical predictions were tested. Starting from the model equations of the adaptive oscillator, an adaptive frequency source coupled oscillator circuit was designed that can be implemented using physical electrical components and this circuit was tested using PSpice simulation program.
