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.

已知某系统传递函数G,可以调用改代码对系统进行降阶处理。功能同routh降阶相似,不过这里的分子阶次r和分母阶次k可以不止相差1。

G UILLAIN-BARRéSYNDROME(GBS)is an uncommon disorder,but one whose impact is far out of proportion to its incidence.Despite a usually good prognosis,GBS is a particularly frightening and often life- altering experience for those diagnosed with the disorder.Many patients are acutely aware of the rapid loss of control of their muscular function, including vital functions such as breathing and swallowing,and fre- quently feel that they are dying.The experience is almost as unnerving for the families of affected individuals.During the acute phase of the ill- ness GBS patients experience the indignity of helplessness in addition to their fear of death or permanent disability.Prolonged disability is com- mon and some permanent residual effects are becoming increasingly recognized.It has been our experience in meeting patients at support groups,that individuals who have been affected by GBS have a great desire for a better understanding of the disorder,even years after the acute experience.

P3.18. An analog signal xa(t) = sin (100πt) is sampled using the following sampling intervals. In each case plot the spectrum of the resulting discrete-time signal. Ts= 0.1 ms, Ts= 1 ms, Ts = 0.01 Sec

P3.20. Consider an analog signal xa (t) = sin (2πt), 0 ≤t≤ 1. It is sampled at Ts = 0.01, 0.05, and 0.1 sec intervals to obtain x(n). b) Reconstruct the analog signal ya (t) from the samples x(n) using the sinc interpolation (use ∆ t = 0.001) and determine the frequency in ya (t) from your plot. (Ignore the end effects.) C) Reconstruct the analog signal ya (t) from the samples x (n) using the cubic spline interpolation and determine the frequency in ya (t) from your plot. (Ignore the end effects.)

一个四位二进制加/减运算器。 要求:当控制端G=0时做加运算,G=1时做减运算。用发光二极管表示运算结果的正、负。用数码管显示运算结果:加运算时,相加之和不超过15,减运算时,结果可正可负,但都用原码表示。
