THEORY: DIFFEERENTIATOR: The differentiator circuit performs the mathematical operation of differentiation; that is, the output waveform is the derivative of the input waveform. The differentiator may ...

Abstract: This paper presents a new technique to improve noise immunity of the RX sensing circuit of mutual-capacitance large touch screen panel (TSP). A differentiator circuit is incorporated to ...

Abstract: A multichannel photonic temporal differentiator implemented based on a single multichannel fiber Bragg grating (FBG) for wavelength-division-multiplexed (WDM) signal processing is proposed ...
