Broadband instruments are velocity sensors, which record data over a large range of frequencies (typically tens of Hz to around 0.01 Hz or lower). Early observatories would typically consist of multiple instruments sensitive to various frequency bands to replicate a broadband overall response. Because different Earth processes excite energy at various frequencies, understanding and broadening the response spectrum of instruments allows for observing more phenomena. Topics explored include the follwoing.
