Hi,
I need some help wit some calculations on filters....
For a woofer, simple L R circuit in series (taking the speaker as R). If the frequency transfer function:
H=(V across R) / (V across L and R)
So i get:
H=IR/[I*(R+JwL)] Where Z=R+JwL
R=8 Ohm L=2.5mH but am not given w so how do I work it out?!!
Also, How do I find the break (3dB) frequency of the transfer function??
Any help would be great cheers!!
