ME360 homework assignments, Spring 2010 HW2, Feb. 1, due Feb. 5 Reading Continue reviewing ME340 and ECE 205/206 material. Text 1: Ch. 1; Ch. 2, Ch. 3: 3.0 - 3.4, review the first and the last pages (mathematical notation, trig. identities, integrals, finite sums, sequences and series, series expansions). Text 2 (Cochin): Ch. 12, sec. 12.1 (modeling review). Problems 1. a) x(t)=sin(15 t)sin(15t), b) x(t)=sin(33 t)+sin(34 t). 2. For the signal x 1 = x(-0.1(t+14)). 3. a) x(t)= -8δ(-10t-14), b) x(t)= -9comb(0.5t)tri((t-7)/16). 4. a) 14 1 (5 8exp( 5 )) ( 12) t t dt

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....
