Moze li neko da mi kaze da li su ove formule tacne. nasao sam ih gledajuci nesto na netu, lik je dao ispod neki primer koji kad se proracuna nema veze pa pitam zbog toga, jer ne znam da li je greska u primeru ili u formulama:
formule:
R=1.25 X Re
C=Le/R2
C = Capacitor value in farads
R = Resistor value in ohms
Re = DC resistance of voice coil in ohms
Le = Voice coil inductance in henries
i njegov primer:
The Morel woofer has a DC resistance of 5.2 ohms and a voice coil inductance of .35mH or .00035 henries. So our Zobel network works out to be .0000129 farads or 12.9uF cap in series with a 6.5 ohm resistor.
In practice these values are approximate, and you may want to experiment, particularly with the value of C.
a ispod jos kaze:
If the driver's DC resistance or voice coil inductance is unknown, just use the nominal impedance for the value of R (8 ohm driver, use an 8 ohm resistor). The value of C for woofers is generally between 10uF and 50uF. For 5-1/4" to 8" woofers, try 10-20uF. 10" to 12" woofers, 20-25uF. 15" to 18" woofers, 30-50uF. Using this criteria for our Morel woofer, our Zobel would be a 15uF capacitor in series with an 8 ohm resistor. Pretty close to our calculated values!
necu da ulazi u to da li "zobel" koristi ili ne tj. treba ili ne treba samo me interesuje
da li su formule tachne.
