Tuning of leapfrog multiple loop feedback bandpass filters - Moritz, Sun - 2001 () Citation Context ... switches used in the implementation. If direct tuning approach is chosen to tune individual biquads to achieve the tuning of overall filter response; switches have to be used to isolate ...
A bandpass filter 940 is used to filter one of the two outputs of the PBS 930 so that the power levels of the noise power levels in two output beams are different while the power levels of the signals in the output beams are essentially unaffected by the filtering. As illustrated, the ...

We are building a multi-channel signal conditioning circuit, in which a Multiple Feedback Band Pass Filter is included for every channel. The frequency-phase curve shows a linear relationship near the central frequency zone, with a very large negative slope, this means if ...
A method is described for determining multiple loop feedback topologies which yield minimum sensitivities for symmetrical, all-pole bandpass filters. The procedure begins with a follow-the-leader feedback (FLF) topology and additional feedback loops are constructed until minimum sensitivity is achieved....
A unified treatment is presented of the effect of both linear and nonlinear imperfections in an operational amplifier on the frequency response of a bandpass multiple-negative-feedback active filter. Linear computer models and describing-function techniques are used to evaluate performance for comparison...
In an active RC filter arrangement comprising bandpass filters (I, II) with multiple negative feedback, for use in ripple control systems, the temperature coefficient of the resistor network (2 to 5 and, respectively, 102 to 105) provided for the frequency adjustment of each of the bandpass ...
It is actually the FIR filter with zeros obtained from resonator poles by the common feedback. The polynomial 𝑃𝑚(𝑧−1)Pmz−1 consists of all resonator poles, excluding poles 𝑧𝑚zm. Equation (4) can be written in a matrix form as follows: 𝑇𝑄𝑚,0(𝑧−1)=𝒂...
