Next, the input signals can be time weighted filters at user choice  


Time domain integrator filters:
*A, B and C weight filters : These filters available in acoustic frequency range (i.e. from 20 Hz to 20 kHz) satisfy requirements from last standards IEC 651 type 0 and IEC 804 type 0.
 
* any other NVgate filter need to be aplly on Front end (real time) or Player (post analyisis). most common are  integrator filters: Single or double time integrators
Single or double time integrators are based on third order high pass filters and the low frequency cut off is automatically adjusted to frequency range.
 
The error on frequency response for a single integrator is less than 0.02 dB for frequencies less than 4 kHz and less than 0.15 dB for frequencies greater than 4 kHz.
