Discrete-Time Signals 41 Plot the PSD (power spectral density) of each signal. Use a binary rate of 1,000 symbols per second and a sampling frequency of 10 KHz. 11. 12. 10. A chaotic signal generator can be set up using Lorentz’s equations: d x = 10( y − x ) ° °dt °d y = 28 x − y − xz ® ° dt °d z 8 = xy − z ° 3 ¯dt The code below generates a chaotic signal using a MATLAB integration method, and shows its behavior in time and frequency domains. 13. 11. The MATLAB code below is aimed at comparing the spectral representation of a 1D discrete-time signal to that obtained when it is periodized.

8. Inappropriate choice of the sampling frequency makes two different sinusoids appearing as opposite phase signals 2. Generate and plot a sinusoid of 356 Hz sampled at 256 Hz, etc. 9. 8. A chirp pulse of width T can be expressed as: x ( t ) = A0 cos φ ( t ) , where the instantaneous phase is given by: φ ( t ) = Ω0t + β t 2 . A linear variation of the instantaneous frequency Ω(t ) during the time support T is then obtained according ( ) to: Ω ( t ) = dφ ( t ) /dt = Ω0 + 2β t , where β = ΔΩ / ( 2T ) = Ω f − Ω0 / ( 2T ) .

1. The MATLAB code below generates and plots some basic discrete-time signals. 1. 2. 40 . 2. Real and imaginary parts of a complex discrete-time signal K is a constant amplitude factor and Re{c} sets the attenuation, while Im{c} is related to the dumped signal period (12 points per period). 3. 100 . 3. 4. 005 s. 4. Spectral aliasing illustration A spectral representation provides information about the variation rate of the corresponding signal in the time domain. The more extended the signal spectrum, the faster the signal temporal variation is and the higher the sampling frequency has to be in order to avoid information loss.
