pow2db
Builtin index · Signal processing
result = pow2db(x)
Input: x · Output: result
What it is
x: a number or vector (power ratio).
Overloads
One call shape — this function is not overloaded.
| Code | Input | Output | Description |
result = pow2db(x) | x number or vectornot documented yet | result — | Returns the same shape: 10*log10(x). POWER-domain convention. |
Examples
From the documentation, and run by the build -- the output and the figure below are what the engine actually produced. Simplest first.
print("{mag2db(2)} dB") # 6.0206 -- a factor-of-2 voltage ratio
print("{pow2db(2)} dB") # 3.0103 -- a factor-of-2 power ratio
output
6.0206 dB 3.0103 dB
