Unformatted text preview: 5.5kHz to 7.5kHz (centered at 6.5kHz). Your job is to design a radio tuner that is able to listen to these two AM radio stations. Hint: You can use two ideal low-pass filters to construct an ideal band-pass filter. Note: the frequency between 5kHz and 5.5kHz is not utilized and serves as a “frequency guard band,” which is a common practice in real applications. Deliverables: Print one figure for each objective, respectively. Objective 1: Reconstruct the music sent by radio station 1 (3kHz – 5kHz) and store it as x1. Listen to it. Use the following commands to plot the corresponding acoustic signal x1(t) and print it down. wavplay(x1,f_sample) plot(t, x1); axis([-2.28, -2.255, -0.08 0.08]); Objective 2: Reconstruct the music sent by radio station 2 (5.5kHz – 7.5kHz) and store it as x2. Listen to it. Use the following commands to plot the corresponding acoustic signal x1(t) and print it down. wavplay(x2,f_sample) plot(t, x2); axis([-2.28, -2.255, -0.08 0.08]);...
