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 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...
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....

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 ...
An optical bandpass filter (BPF) is employed to remove out-of-band amplified spontaneous emission (ASE) from the EDFA. The optical signal is coupled in and out of the proposed SiPh MDM power distributor using on-chip grating couplers (GC). During NOMA operation, the Rx simultaneously ...
The filter is then applied to bandpass the SRBR modes for the individual source, and the noise in the stop band of the wavenumber axis could be filtered out, which is beneficial for improving the ranging accuracy. Then, a recognizable intensity spectrogram contributed by one source is obtained...
