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 ...

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.
