PROGRAM ARC-FILTER Russian patent published in 1995 - IPC

Abstract RU 2040853 C1

FIELD: radio engineering. SUBSTANCE: device has first operational amplifier, first controlled digital-to- analog converter, first integrator, second controlled digital-to-analog converter and second integrator which are connected in series. In addition device has three resistors. Each integrator has two operational amplifiers, two capacitors, two resistors. Seven resistors and fourth amplifier are introduced to accomplish the goal of invention. Controlled digital-to-analog converters are made in digital-to-analog converter and additional operational amplifier which are connected in series. In addition fourteenth register is introduced. EFFECT: increased range of operation frequencies, increased precision of setting pole frequency. 2 cl, 1 dwg, 2 tbl
