I don't see how forcing anything to a higher output power creates cleaner signals man...
Impedance matching is usually done at the cable/board level to maximize power transfer. To match the characteristic impedance (Zo). The ER-4 from Etymotic has an impedence adapter (resistive adapter) that acts in conjunction with the capacitance to form a filter that changes the frequency response of the unit using it. |

QUOTE(DaEMoNteNTAcLe @ Mar 11 2010, 04:20 PM) well i couldnt find much info.. that's one of them that i found.. probably.. Attenuation doesn't work that way. Attenuation is a fixed function for the most (sometimes frequency dependent) anyway if talking about signal attenuation.. if the output is not strong enuff.. there will be some attenuation, or frequency drops..  If you have a level of attenuation, the signal will be attenuated by that level only. eg; an Attenuation of 1 dB, so if you put 10 dB in, you come out with 9 dB, if you put in 40dB, you come out with 39 dB. Something like that. |
