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.
Dialog Box
