Abstract

PURPOSE:To prevent mistracking by using switched capacitor filter for the prediction circuit. CONSTITUTION:The digital output D of the flip-flop 104 is also fed to the integrating circuit 105 consisting of the switched capacitor from the terminal 1, it is converted into analog output C with integrating action, the prediction output B to the analog input signal A with the auxiliary integrating circuit 106 is produced and compared with the analog input signal A with the comparison circuit 103. The result of comparison is sampled at the flip-flop 104 and output from the terminal 102.
