Document Summary

Fall 2002 (a) what is the equation describing x(jw)? jx. 20 (g) from transform #9 in table 4. 2, tb. L d dt v out jw t v. L t out t jw d dt v in (c) skip (d) jwh. N=sqrt(4/10)=0. 63 (e) this is a band pass filter. 53. 1 yss(t) = 3*0. 01cos(10t+15 -87. 7 ) = 0. 03cos(10t 72. 7 : for the transfer function sh s. Re{s} -1 h1(t)= e-tu(t) so. Re{s}>-1 : for the transfer function h(t)= -e-3tu(-t) -e-tu(-t), h(t)= e-3tu(t) -e-tu(-t) h(t)= e-3tu(t)+ e-tu(t) not stable not stable stable not causal not causal causal. Real: sketch the pole-zero plot for this transfer function. Stop band filter (i would accept high pass filter with the appropriate. 1 explanation): if x(t)=e-5tu(t) and y(t)=3e-5tu(t)+e-2tu(t), what is h(t) 10: let x[n] = (-1)nu[n] + anu[-n-n0]. Determine the constraints on the complex number a and the integer n0, given the roc of x(z) is 1 < |z| <2 .
