PROBLEM Spring-09-Q.2.1: (a) For the system described by the difference equation: yOEnŁ D 1:5xOEnŁ C 3:5xOEn 2xOEn , determine the output when the input is xOEnŁ D 2ıOEnŁ C 2ıOEn C 2ıOEn C 2ıOEn C 2ıOEn . Give your answer as a stem plot. - 6 0 1 1 2 3 4 5 6 7 n Label all points (b) When the M ATLAB command soundsc(xx,44000) is used, the highest frequency that can be heard is Hz. (c) The signal x.t/ is bandlimited to 15;000 Hz, i.e., it has no frequency components for f > 15;000 Hz. The Nyquist rate for sampling x.t/ is samples/sec.
(d) Determine the impulse response of the FIR filter defined 3 in M ATLAB via: yy = firfilt( [0,0,0,0,0,-0.1,0,-0.3,0,0.5], xx ); Express your answer as a sum of shifted unit-impulse signals. (e) Make a stem plot of the signal sOEnŁ D 7.uOEn uOEn 7Ł/ , where uOEnŁ is the unit-step signal. - 6 0 1 1 2 3 4 5 6 7 n Label all points 3 In M ATLAB , the functions firfilt and conv are equivalent; they produce the same result.
