An X-band frequency doubler MMIC with a newly developed, small, 2-band elimination filter is presented. The filter consists of two miniaturized stubs and lumped capacitors and suits MMIC implementation. The line impedance and lengths of the stubs can be decided independently and the capacitance values are simple to calculate. The concept of the filter is(More)
Electroencephalograph (EEG) recordings during right and left hand motor imagery can be used to move a cursor to a target on a computer screen (such system is called BCI). Recently, we have proposed the detection method of Error Potential in order to add the fail safe function to BCI system. In this paper, feature extraction method based on morphological(More)
