Abstract (2. Language): 
Sources of the errors and compensating methods at multi-channel analog-to-digital convertor (ADÇ), in which an output signal is a many-dimensional array or set of the one-dimensional arrays, are considered. The source of the error in the common sample-and-hold (SH) circuit of the modern ADÇ for several channels is analyzed. Methods of errors compensation in time and frequency domains for the algorithm of geometrical coordinates of a signal source determining are analyzed.
Abstract (Original Language): 
Çıktı sinyalinin cok boyutlu dizin veya bir cok tek boyutlu dizinler seklinde olduğu, cok kanallı analog sayısal cevirgec (ADÇ)'lerde hataların kaynakları ve telafi yöntemleri dikkate alınmıştır. Analog sayısal çevirgeçlerde yaygın olan bir cok kanal icin ornekle ve tut devresinde hata kaynagı analiz edilmistir. Sinyal kaynagı'nın geometrik koordinatları algoritması zaman ve frekans bölgesinde hataların telafi yontemleri analiz edilmistir.
