Input x is the sampled signal vector, may have both AC and DC components. output vector y should have AC components removed then change sign alternately, for example, input [1:5], output [3 -3 3 -3 3].
Could you be a bit more specific about the specs? What exactly are we supposed to do here?
Distance walked 1D
matrix of natural number
Create incrementing array
Generate one sample of uniform random numbers between -pi and +pi
Filter AC, pass DC
