function LogAmplt(Base: Double; Span: Double; aMax: Double; aScale: Double; Normalized: Boolean): Double;
Compute the logarithm of the amplitude spectrum and convert to dB.
| # | Name | Type | Description |
|---|---|---|---|
| 1 | Base | Double | scalar |
| 2 | Span | Double | scalar |
| 3 | aMax | Double | scalar |
| 4 | aScale | Double | scalar |
| 5 | Normalized | Boolean |
Returns: Double
Remarks:
Base defines the base of the logarithm (usually 10). Span defines the span in dB of the result, and AMax is the maximum amplitude found in the spectrum. If Normalized is True, the highest value of the spectrum will positioned at 0.
