# Baseband Data

Nyquist-sampled, band-limited data, sometimes called “voltage data”. The sample rate is twice the bandwidth of the signal, so this tends to be very voluminous data – data rate is twice the bandwidth times the bit depth (sample size) – but it allows for complete reconstruction/characterization of the original analogue signal. Our data are typically not baseband data, although it is used for some searches (typically checked in real-time and only kept if promising).
