Hi, 
I am Working on Designing a Graphic Equalizer on MATLAB.
And, right now thinking of how to do the testing !!

Anybody know how to do Graphic Equalizer testing .. ?

While googling, i came accross a link which says like .. 

1)Frequency Response  Good 30-20kHz +0.1, -0.3 dB  
2)1 kHz Total Harmonics Distortion  Excellent 0.0015% @ 0 dB  
3)Signal to Noise Ratio  Excellent 88 dB  
4)19 & 20 kHz Intermodulation Distortion  Excellent 0.011% @ -1.5 dB  
5)Dynamic Range  Excellent 90 dB 
6)Jitter Distortion  Excellent <-117 dB  

alond with the graphs !

the link is ..

Will the same work for the "digital Graphic Equalizer" also ?

Any more lights in to this topic ??? 
thanx in advance !
	regards,
sher
