Fig. 1From: Sexual dimorphism in echolocation pulse parameters of the CF-FM bat, Hipposideros pratti The sonogram (a) and power spectrum (b) of a representative echolocation pulse emitted by a hanging Hipposideros pratti. The CF (kHz), FM bandwidth (kHz), CF duration (ms), and FM duration (ms) of this echolocation pulse were 60.0, 12.8, 7.5, and 2.7. Clearly, the second harmonic is the predominant one that contains the highest energyBack to article page
