# RMS Lim/Exp
This block implements the code found [here ](http://spinsemi.com/get_spn.php?spn=rms_lim_exp.spn\&prodnum=SPN1001)in the Spin Semiconductor Free Programs.
It looks like it limits the input signal to -12 dB FS. The tones shown below are at 110, 440, and 2200 Hz. Top trace is input, bottom trace is output.

The expansion can be seen in the next image. The input signal (top) is white noise at 10 dB steps from -60 to 0 dB FS.
