Consider the signal x[n] = cos(Ωn), where Ω=4π/31. (a) Determine an expansion factor L and compression factor M that result in a signal that reduces the sampling rate Fs of x[n] by 40% to 0.6Fs....

(a) Determine an expansion factor L and compression factor M that result in a signal that reduces the sampling rate Fs of x[n] by 40% to 0.6Fs. Choose M and L to be coprime.

(b) Using M and L from part (a), plot the resulting signal at each stage of an implementation that follows Fig. 4.34a.

(c) Using M and L from part (a), plot the resulting signal at each stage of an implementation that follows Fig. 4.34b.
