واضح آرشیو وب فارسی:فان پاتوق: { Abbreviations used in Electronics }
در علم الكترونيك با حروفات مختصري مواجه ميشويد كه معني و مفهوم ان را نميدانيد !!!! بسيار خوب اين حروف با انتخاب اولين حرف از چند كلمه اي كه يك جمله معني داري تشكيل شده است در اصطلاح {ابرويشن } ناميده ميشوند :
در اين تاپيك با تعدادي از اين اختصارات و مفهوم انها بيشتر اشنا ميشويد :
