Frequency-Shaping with Spatial Compensators
Journal of Intelligent Material Systems and Structures, 2000Practical realizations of adaptive structures should be designed and implemented to maximize performance, robustness and efficiency. A method of frequency-shaping the compensation of an adaptive structure is developed for increased performance, system robustness and efficiency.

Frequency response compensation with dsp
IEEE Signal Processing Magazine, 2003In modern telecommunication systems, there are situations when test instruments must work over hundreds of narrowband-frequency channels. It is difficult and expensive, however, to build hardware test equipment with a flat frequency response over their full operational frequency range.

Three stage amplifier frequency compensation
ESSCIRC 2004 - 29th European Solid-State Circuits Conference (IEEE Cat. No.03EX705), 2004This paper analyzes four recent different frequency compensation schemes for three stage amplifier. Under equal conditions it is possible to study the unity gain frequency (UGF) for each scheme without external interferences, such as technology variations or different design criteria and optimization emphasis.

A twice curvature compensated voltage reference with double frequency compensation
Microelectronics Journal, 2020Abstract This paper presents a voltage reference (VR) with low temperature coefficient (TC) and full frequency high power supply rejection ratio (PSRR), the VR is fabricated by 0.18 μm CMOS process. The proposed VR uses different methods to compensate for the temperature curvature of the output voltage twice.

Frequency Compensation for a Self-Mixing Interferometer
IEEE Transactions on Instrumentation and Measurement, 2010Laser interferometry is a well-established technique that is widely used in industrial and laboratory environments to measure displacement, velocity, vibration, and distance. Recently, a new technique based on self-mixing (or feedback) interferometry has been introduced.

An approach to amplifier frequency compensation
IEEE Transactions on Education, 2003In this paper, an approach to the input lag compensation technique is described. The compensating network is explored iteratively, using two programs that take advantage of the graphical user interface (GUI) tools provided by MATLAB and provide a clear insight into the behavior of the network.

Frequency compensated A-C ammeters and voltmeters
Electrical Engineering, 1946The increased use of a-c instruments over a frequency range of 25 to 3,000 cycles for aircraft and industrial applications has imposed new requirements on instrument design. It is recognized that the standard type of a-c ammeters and voltmeters normally calibrated for use at a given frequency are subject to errors in indication when used at other ...

High frequency compensated face hallucination
2011 18th IEEE International Conference on Image Processing, 2011Face Hallucination is, one of a learning-based super-resolution technique that can reconstruct a high-resolution image using only one low-resolution image. However, there are often some detailed high-frequency components of the reconstructed image that cannot be recovered using this method.

Compensated mel frequency cepstrum coefficients
1996 IEEE International Conference on Acoustics, Speech, and Signal Processing Conference Proceedings, 2002The high concentration of energy in the low frequency range observed for most speech spectra is considered a nuisance because it makes less relevant the energy of the signal at middle and high frequencies in many speech analysis algorithms. This problem is often partially solved by filtering the input signal with a single-zero high pass filter.
