The second-order active RC low-pass filter circuit comprises a first resistor (11), a second resistor (12), a third resistor (13), a fourth resistor (14), a fifth resistor (15), a sixth resistor (16), a first capacitor (17), a second capacitor (18), a third capacitor (19), a...
Other chapters briefly introduce a design process of simple second order low-pass and high-pass filter. A theory of current conveyors is discussed too, because they are the basic building blocs of proposed synthetic element and also active frequency filters. Finally, the particular solutions of ...
This paper describes the design method for low-pass filter of second-order voltage-controlled voltage source,and gives its general expression. The design approach is based on the required cut-off frequency; within a wider range from 1:2 to 1:10 to flexibly take two capacitance values,and then...

band-stop and all-pass filter characteristics by suitably choosing the current output branches.The characteristic parameters can also be set orthogonally through adjusting the bias currents of the MO-CCCIIs and the grounded capacitors.The biquad enjoys very low sensitivities with respect to the circuit...
and its filtering effect was compared to the traditional filtering methods such as simple low-pass filter method and software median filtering method.The results show that second-order Butterworth low-pass filtering method not only can filter the useless noise signal,but also can keep the original ...
A New Method for Designing Flat Shelving and Peaking Filters Based on Allpass Filters In this way, it is well known the design of first order shelving filters and second order peaking filters. Additionally, the resulting filter can be ... - International Conference on Electronics 被引量: 0发...
Current Mode FilterSPICEA new current mode 2nd order filteremploying single current differencingtransconductance amplifier(CDTA), using currentmode approach which provides high pass(HP), bandpass(BP), low pass(LP) responses simultaneously,has been presented. The current outputs oflowpass(LP) and ...
