VOLT_TO_DB

Take voltage values and convert them to dB. Equation: f(x) = 20 * log[10](x / ref_value) Params: data : OrderedPair|Vector The input to apply the absolute value to. ref_value : float The reference Returns: out : OrderedPair x: the x-axis of the input. y: the absolute value of the input.

In this example, LINSPACE and SINE generate a sine wave.

We pass those values to VOLT_TO_DB which calculated the dB values from voltages.
