dB Gain
5-120
5dB Gain
Purpose Apply a gain specified in decibels.
Library Math Functions / Math Operations
Description The dB Gain block multiplies the input by the decibel values specified in the
Gain parameter. For an M-by-N input matrix u with elements u
ij
, the Gain
parameter can be a real M-by-N matrix with elements g
ij
to be multiplied
element-wise with the input, or a real scalar.
The value of k is 10 for power signals (select
Power as the Input signal
parameter) and 20 for voltage signals (select
Amplitude as the Input signal
parameter).
The value of the equivalent linear gain
is displayed in the block icon below the dB gain value. The size and frame
status of the output are the same as the input.
