Abstract
A target specific folded analog to digital converter (ADC) is provided, such as for use in a data detection channel in a direct access storage device (DASD). The high speed analog to digital converter (ADC) includes a digital signal decoder for decoding specific target levels of an analog signal. An analog to digital converter section of the ADC converts an analog error signal of the analog signal to digital decoder outputs representing the analog error signal.
