7 -Broadband (or BB) sensors are especially sensitive to low frequency energy, and are //broad//ly defined as any instrument capable of **reliably recording wave periods greater or equal to 10 seconds**. This makes them useful for analysis and detection of teleseismic earthquakes as well as techniques involving ambient noise. However they are also well-suited for measuring high frequency energy, limited only by the Nyquist frequency of the [[data logger>>doc:Instrumentation.Data Loggers.WebHome]]'s sampling rate. The downside to broadband sensors is usually their cost, size, and fragility relative to short period sensors.
