Figure 2: (a) A time-course periodic signal with frequency sampled by the bio-like sampling strategy; 16 time points are assigned to the interval (0,8], and 8 time points are assigned to the interval (8,16]. (b) The periodogram derived using RIAA. The maximum value (peak) in the periodogram locates at frequency .
