bit depth

[′bit ‚depth]
(computer science)
In a digital file, the number of colors for an image; calculated as 2 to the power of the bit depth; for example, a bit depth of 8 supports up to 256 colors, and a bit depth of 24 supports up to 16 million colors.

bit depth

The maximum numeric value in a coding system. The bit depth is the maximum number of bits in the system's storage element and represents either the total number of discrete items that can be represented or the largest magnitude. For example, the bit depth of an audio sample determines its dynamic range (see audio bit depth). The bit depth of a screen pixel determines the total number of colors that can be displayed (see color depth). See bit specifications and binary values.

Previous testers used separate low frequency units to achieve 16 bit resolution, along with higher frequency units with resolutions usually limited to 12 bits.
Parameters are measured with a 4th order Delta Sigma A/D converter, and communicate 16 bit resolution data--true RMS current and voltage, bi-directional active and reactive power, power factor and frequency (up to 19.
