This is caused by the non linear distortion that happens in the ear.
2.
But it's not a change in gain; it's non-linear distortion.
3.
Linear distortion does not introduce new frequency components to a signal but does alter the balance of existing ones.
4.
This results in a constant-modulus signal ( constant envelope signal ), which reduces problems caused by non-linear distortion.
5.
Then, computer software is used to compute a FIR filter, which reverses the effects of the room and linear distortion in the loudspeakers.
6.
Is this a non-linear distortion that could be corrected by modern processing ? talk ) 23 : 57, 11 June 2014 ( UTC)
7.
IIR filters, which are by nature recursive have the drawback that if not carefully designed they may enter limit cycles resulting in non-linear distortion.
8.
These so-called third order distortion products ( third order as m + n = 3 ) tend to dominante the non-linear distortion of narrowband systems.
9.
If " F " is a linear function, for instance a filter whose gain and / or delay varies with frequency, the signal suffers linear distortion.
10.
If non-linear distortion happens to the broadcast signal, the 3.579545 MHz color carrier may beat with the sound carrier to produce a dot pattern on the screen.
