1. Generate a digital sinusoid 0 [ ] : ( ) 0.3sin(2 ) s
s
k
f k f kT f
F
, where 0 f 1kHz and
16 s F kHz by using the following Matlab commands, then plot out and listen to it,
>> k=1:5*16e3;
>> fk=0.3*sin(2*pi*1e3.*k/16e3);
>> stem(fk(1:32))
>> sound(fk,16e3) %adjust the volume as desired
Save the graph plotted and compare the signal waveform to that of fkr16 in PART A,
discuss similarities or differences between both signals in the Lab report. Answer the
question below for what you have heard.
