Converts from decibels to linear units.

Parameters:¶

x: ArrayLike¶

The input value or signal in dB.

type: 'value' | 'power' | 'voltage' = 'value'¶

The type of output value or signal.

• "value": The output value/signal is any value.

\[x_{\text{linear}} = 10^{\frac{x_{\text{dB}}}{10}}\]

• "power": The output value/signal is a power measurement.

\[P_{\text{linear}} = 10^{\frac{P_{\text{dB}}}{10}}\]

• "voltage": The output value/signal is a voltage measurement.

\[V_{\text{linear}} = 10^{\frac{V_{\text{dB}}}{20}}\]

Returns:¶

The value or signal in linear units.
