Mesfet small signal transfer functions

Microwave and Optical Technology Letters, 1990
AbstractThis article presents a signal flow graph representation for a microwave MESFET equivalent circuit. The model has been found to provide accurate fits to NE71000 MESFET chip scattering parameters; typical results are shown. Four symbolic transfer functions are presented which allow device scattering parameters to be computed.

Signal Transfer Function of Optical Components*

Journal of the Optical Society of America, 1970
The effect of an optical component or subsystem on an electromagnetic wave is considered and a signal transfer function associated with the propagation is derived. A coordinate transformation is introduced which makes it possible to compute this transfer function.

The effect of magnetization transfer on functional MRI signals

Magnetic Resonance in Medicine, 1997
AbstractA magnetization transfer (MT)‐prepared echo‐planar imaging (EPI) pulse sequence was developed to study motor cortex activation, using a finger tapping paradigm. MT weighting resulted in a reduction of both the activated area and, in the majority of activated pixels, the functional MRI signal, regardless of the correlation coefficient threshold ...

Inertial sensor signals denoising with directed transfer function

2015 9th International Symposium on Advanced Topics in Electrical Engineering (ATEE), 2015
In order to achieve precise navigation information on the displacement of a vehicle in terms of position, speed, acceleration and direction we are suggesting the use of a new software procedure for processing data received from miniaturized inertial navigation systems.

Measurement and comparison of modulation transfer function and signal transfer function of image intensifiers

SPIE Proceedings, 2000
The performances of the 3rd generation and Super generation image intensifiers were measured and analyzed about two kinds of transfer functions, including Modulated Transfer Function (MTF) and Signal Transfer Function (SiTF). It was summarized that the change tendency of this two kind functions under different illuminances and color temperatures.

Signal Processing for Modulation Transfer Function Test Bench

2011 Symposium on Photonics and Optoelectronics (SOPO), 2011
The signal processing flow for the MTF test bench that is based on Fourier analysis method is presented. The signal processing flow mainly consists of three parts that are Fourier analyzing, background correction and system attenuation elimination. The center of the pinhole area is recognized automatically and the line spread functions (LSF) of both ...

Sterol Carrier Protein-2 Functions in Phosphatidylinositol Transfer and Signaling

Biochemistry, 2003
Over 20 years ago, it was reported that liver cytosol contains at least two distinct proteins that transfer phosphatidylinositol in vitro, phosphatidylinositol transfer protein (PITP) and a pH 5.1 supernatant fraction containing sterol carrier protein-2 (SCP-2).
