The signal processing block
Average can either calculate the linear or exponential average of an input.
It is based on IEC 61672-1:2013 which specifies sound level meters
and defines the time-weighted sound level.
The input is
MxN and must be a time signal with the units
The output is
KxN which is an average of the input signal
MxN. The size of
K is dependent on the type of averaging
and the time constant. The unit of the output is the same as the input.
|Time constant||125.0 ms|
Name specifies the name of the block.
Type specifies the type of time averaging is performed. The type can either be
Time constant specifies the averaging time of the block in either
Windows specifies the type of window used when time averaging.
Overlap specifies the overlap in time, when using a linear averaging, in either
Channels specifies the number of input(s)/output(s) the block will have.
This examples show the difference between a linear and exponential time average on a 10 Hz tone.
