Device for determining pick-up head tracking error in a digital tape player

Image Number 6 for United States Patent #4891644.

An analog-to-digital converter suitable for digitalizing signals used in an automatic track finding mechanism of a digital audio tape-recorder. The A/D converter comprises a sampling clock generation circuit for generating a sample clock in synchronism with an input signal and an analog-to-digital conversion circuit for analog-to-digital converting an amplitude peak value of the input signal at a timing of the sampling clock. The A/D converter is samplified in structure, for the sampling clock for sample holding does not have to be quartz oscillated but only needs to be a signal synchronous to the input signals.
