Question

please answer all parts with explaining to study it with clear hand writing

Two sinusoid signals are defined as x2 (1)-4cos (2π10t) 4(1)-2sin (16m) a) Find all the frequencies of y(r) (List only frequencies in y(i)) b) What is the minimum sampling rate to avoid aliasing in the y(t)? c) If fs 40, find a the frequencies and the corresponding magnitude values (don't worry about the phase values) (make sure it is now in the discrete time domain) d) If fs-10, find all the frequencies and the corresponding magnitude values (don't worry about the phase values) (make sure it is now in the discrete time domain)
