Definitions of Units
dB0 | Level in decibels, referred to a full scale sine wave |
| in a sampled system. So, 0 dB0 is full scale. |
dBu | Level in decibels, referred to a 0.775V rms sine |
| wave, with no external loading (u = unloaded). |
| The level of 0.775V is derived from the older dBm, |
| for which the reference level is 1mW of signal |
| power into a 600Ω termination from an output with |
| 600Ω source impedance. |
dBV | Level in decibels, referred to a 1.0V rms sine wave, |
| with no external loading. |
kS/s | Sample rate in |
| replaces kHz which is technically incorrect when |
| referring to sample rates. |
ADC | Analogue to Digital converter, also known as an |
| A/D |
DAC | Digital to Analogue converter, also known as a D/A |
DDC | Digital to Digital converter – used for format |
| conversion and some DSP operations that change |
| the data. |
