Use as an example the product of cosines. 10. Take signal x 1 (t) = 6x(0.6t) where x(t) is given in Fig.2, and work out models in a), b), and c) for signal x 1 (t). 11. Show this for signal y(t)= sin(16 t-/8). 12. a) 100 Hz, b) from 10 Hz to 700 Hz in 30 seconds. 13. x(n)=5tri(n/18)sinc(n/20). 14. Take y(n)=6x(-(n+18)/8) linear interpolated....
