Characteristics of the Receiving System for Complex Signals

  • Chapter
The Sonar of Dolphins

Abstract

The discussion of the dolphin’s receiving system so far has dealt primarily with relatively simple sinusoidal signals. In this section, we will discuss characteristics of the dolphin’s receiving system for complex sounds. Any broadband, nonsinusoidal sound, such as a short click, a combination of clicks, or broadband noise, is defined as a complex sound. Since we will not discuss the characteristics of dolphin sonar pulses until Chapter 5, it is sufficient to state at this time that dolphins typically echolocate with short duration broadband transient-like pulses or clicks. In fact, the experiments that will be discussed in this section were performed to answer questions concerning various facets of the dolphin’s echolocation capabilities; however, since they were hearing or passive sonar experiments and measured the characteristics of the animals’ receiving system, it is appropriate to present them here.
