a. A television content producer in Accra wants to store music digitally on a CD. How would he do it mathematically, if the sampling frequency, Fs is 0.6 kHz and the analog signal is x,(t) = 2cos(500nt) – 3sin(1000nt)+ cos(1500t) Also explain mathematically how he can determine the continuous time signal y.(tater the reconstruction. Is the signal at y,&qual to the signal at x,(t)? Explain. b. Explain using the appropriate diagrams, transfer functions and mathematical tools the difference between modern control and classical control systems. c. After sampling of analog signals, the following output conditions were observed (fs22fc), (fs=2fc), and (fsS2fc), draw signals to indicate these three scenarios. Identify these signals by their names and explain the difference between them.

QUESTION TWO a. A television content producer in Accra wants to store music digitally on a CD. How would he do it mathematically, if the sampling frequency, Fs is 0.6 kHz and the analog signal is x.(t) = 2cos(500nt) – 3sin(1000nt)+ cos(1500nt) Also explain mathematically how he can determine the continuous time signal y.(t)after the reconstruction. Is the signal at y.qual to the signal at x.(t)? Explain. b. Explain using the appropriate diagrams, transfer functions and mathematical tools the difference between modern control and classical control systems. 2 c. After sampling of analog signals, the following output conditions were observed (fs22fc), (fs=2fc), and (fss2fc), draw signals to indicate these three scenarios. Identify these signals by their names and explain the difference between them. d. A system is defined by A and B: where [3 1] [4 -21 B = and A = l2 li 3 i. In this experiment, show that D= (-2+j3) A+B Show the reason why one can write N = i.
