Consider a continuous-time ideal high-pass filter that removes all frequencies below a given cut-off frequency, and allows all frequencies at or above that cut-off frequency to pass through the system unchanged. That is, the filter will keep frequency w if w] 2we and remove frequency w if ww Let the cutoff frequency we have value 2π.a) Sketch this filter's frequency response H(ju). (b) Let x(t) 4-3 cos(3m) + 6eMt. Find ak, the Fourier series coefficients of x(t) (c) Now, let r(t) (defined as in part b) be the input to this high-pass filter. Let y(t) represent the filter's output, and let bk represent the Fourier series coefficients of y(t) Write an expression for bk (d) Write an expression for y(t)

Ariver flows from north to south at 8 km/h. a boat is to cross this river from west to east at a speed of 20 km/h (speed of the boat with respect to the earth/ground). at what angle (in degrees) must the boat be pointed upstream such that it will proceed directly across the river (hint: find the speed of the boat with respect to water/river)? a 288 b. 21.8 c. 326 d. 30.2
