Zusammenfassung:In this paper the rst measurements results of an analog current-mode 2-D DCT test chip are presented. The circuit performs 4-point transform and the measured results con rm the correct operation of the circuit. Moreover, the accuracy of the results is on acceptable level and ful I the imposed requirements in this respect.
