The phrase "an active feedback" is not correct in standard English; it should be "active feedback" without the article "an." You can use "active feedback" when discussing a process or system that involves ongoing, responsive communication or evaluation.
Example: "The team implemented active feedback mechanisms to ensure continuous improvement in their project."
Alternatives: "dynamic feedback" or "ongoing feedback."
HTS magnetic bearings are inherently stable without an active feedback system.
The work proposes a novel linearization technique for high-frequency wide-band applications using an active feedback as post-distortion.
This work proposes an active feedback control strategy using cross-correlation technique in a single stage axial flow fan operating under dynamic inflow distortion.
The compensation schemes exploit a single Miller capacitor and an active feedback to form the main negative feedback loops for pole splitting and two feedforward paths.
The reactive gas flow during the sputtering processes was either controlled by direct mass flow rate (i.e. constant reactive gas flow) or by an active feedback process control system.
The proposed resonator uses an active feedback loop with a microwave amplifier to generate negative resistance to compensate the resonator's loss and increases the loaded quality factor of the system.
(i) First, an active-feedback electronic device was home-built to generate feedback fields from the received FID current.
(ii) Next, an active-feedback pulse sequence was developed to enhance the contrast originated from local magnetic-field gradient variations due to Gd-nanoparticles.
An active-feedback closed-loop x-y-scanner with a scan range of 100 × 100μm enables the instrument to rapidly record large area scans using confocal microscopy.
They are a by-product of a vulnerable active feedback mechanism, located in the cochlear outer hair cells, which contribute greatly to the remarkable sensitivity and frequency discrimination of hearing (Kemp 2002).
We found no convincing evidence of improvement in the reporting of CAM during the study period, but a controlled parallel intervention, or formal time series analysis of a more active feedback program would be needed in order to draw any confident conclusions about the potential for improvement.
