i'm a b.tech student and i'm interestsd in doing a semi project in signal processing.But i don't have much idea on it.so,can you please send me some easy mini projects on signal processing or matlab projects with required programs,figures,diagrams as early as possible!!
or
can you please send me the matlab program on the given topic:
'Write a program to modulate the two-bit data stream into a 4-FSK signal at four suitable frequencies. The output of the modulator should be sent to the analogue output.
Solution:
Firstly, we generate four suitable frequencies f1,f2,f3 and f4 as the orthonormal basis functions ( f1 = 1000; f2 = 1500; f3 = 2000; f4 = 2500; ) to represent four sinusoidal waves . And then the sine wave is stored into a 16 length of array s[i]. The sinusoidal wave is changing the frequency when two buttons (two-bit analogue output) is pushed.'
