  • 用外部设备设置32位微控制器TriCore的中断的指令及方法

    The Infineon TriCore provides an Interrupt System with a high safety standard. Thisdocument contains some instructions on how to initiate an Interrupt from an externaldevice. First it will show you how to trigger an Interrupt Service Request by an impulseon Port 0 or Port 1. Then in the second part of the document you can find hints how todebounce impulses to enable the use of a simple switch as input device.Authors: Thomas Bliem, CQ Nguyen / Infineon SMI MD Apps

  • The Window Design Method The basic idea behind the design of linear-phase FIR filters using the win

    The Window Design Method The basic idea behind the design of linear-phase FIR filters using the window method is to choose a proper ideal frequency-selective filter [which always has a noncausal, infinite duration impulse response] and then truncate its impulse response hd[n] to obtain a linear-phase and causal FIR filter h[n]. To truncate the impulse response of the ideal filter a time window w[n] is used. Available windows in Matlab are rectangular [or boxcar in Matlab], bartlett, hamming, hanning

  • The Hilbert Transform is an important component in communication systems, e.g. for single sideband m

    The Hilbert Transform is an important component in communication systems, e.g. for single sideband modulation/demodulation, amplitude and phase detection, etc. It can be formulated as filtering operation which makes it possible to approximate the Hilbert Transform with a digital filter. Due to the non-causal and infinite impulse response of that filter, it is not that easy to get a good approximation with low hardware resource usage. Therefore, different filters with different complexities have been implemented. The detailed discussion can be found in "Digital Hilbert Transformers or FPGA-based Phase-Locked Loops" (http://ieeexplore.ieee.org/xpl/freeabs_all.jsp?arnumber=4629940). The design is fully pipelined for maximum throughput.
