Waterfall plots are often used to show how two-dimensional phenomena change over time. [1] A three-dimensional spectral waterfall plot is a plot in which multiple curves of data, typically spectra, are displayed simultaneously. Typically the curves are staggered both across the screen and vertically, with "nearer" curves masking the ones behind.
Spectrogram (waterfall display) of an Olivia 16/500 signal centered on 7073.25 kHz Olivia MFSK is an amateur radioteletype protocol, using multiple frequency-shift keying (MFSK) and designed to work in difficult (low signal-to-noise ratio plus multipath propagation) conditions on shortwave bands.
A waterfall display depicting several PSK31 transmissions at around 14,070 kHz. The green lines indicate a station that is transmitting. PSK31 or "Phase Shift Keying, 31 Baud", also BPSK31 and QPSK31, is a popular computer-sound card-generated radioteletype mode, used primarily by amateur radio operators to conduct real-time keyboard-to-keyboard chat, most often using frequencies in the high ...
PQ is the basis of HDR video formats (such as Dolby Vision, [2] [9] HDR10 [10] and HDR10+ [11]) and is also used for HDR still picture formats. [ 12 ] [ 13 ] PQ is not backward compatible with the BT.1886 EOTF (i.e. the gamma curve of SDR ), while HLG is compatible.

They are identical OETF based on a gamma curve and used for SDR-TV. [3] [2] [4] BT.1886: The ITU-R Recommendation BT.1886 is the reference EOTF of Standard Dynamic Range TV (SDR). [5] sRGB: sRGB defines a transfer function based on a gamma curve and used for monitors, printers and the Web. sRGB is standardized as IEC 61966-2-1:1999 [6]
