decibel: Conversion to decibels

In ifultools: Insightful Research Tools

Description

Convert numeric input into decibels.

Usage

decibel(x, type=1, na.zero=TRUE)

Arguments

x	a real positive numeric value.
na.zero	logical value controlling the handing of zeros in the data. If TRUE, the zero values are replaced with NAs prior to converting to decibels, avoiding an error when attempting to take the logarithm of zero.
type	an integer signifying the decible form to use in the conversion. If type=1 10 * log10(x) is used to convert the input and 20 * log10(x) isued for type=2.

Value

the decibel equivalent of the input x.

Examples

decibel(c(1,10,100,1000), type=1)
decibel(c(1,10,100,1000), type=2)

Example output

[1]  0 10 20 30
[1]  0 20 40 60
