to be honest this is all a little over my head many thanks for your help, but i think its best if i go back to my lecturer tomorrow and ask if he can explain it thanks again blair

in series there is one L, one R and one C

exscuse my ignorance topology?

apologies i am looking for the resonant frequency and the band witdh

my problem is that i cannot find the equation this i what i was asking for i cannot get started if i cannot find the equation

hi there ive been attemping this question and i cannot find the equation to work it out anywhere ! any help would be great ! for a passive band pass filter from the following list choose the three components which would produce a cut off frequency closest to 7 khz and a band width...

the formula i need is for a passive band pass filter

does anyone know the formula for band pass filters. thanks

many thanks for all your help, i think you may have just saved my academic life. blair

many thanks

yes i have tried plugging them into the formula, my problem, i am having trouble getting the decimal places in the right places.

im sorry if this is lame for you guys but i posted a thread for some info on farads and the info was good but i still cannot find the answer to this question any clues for a low pass filter from the following list choose the two components which would produce a cut off frequency...

warren you are the best

hi there if anyone could help i would be very grateful for a low pass filter from the following list choose the two components which would produce a cut off frequency closest to 100 khz resistor capacitor 1.6 k ohm 1 nf 33 k ohm 330 nf 150 k ohm 10 uf...

hi there i would be very gratefull if anyone could help. im trying to work out some values for a low pass filter. the problem is the values for the capacitor I am not sure exactly what amount nf or uf are, for example 1 nf or 10 uf what is the exact number any help would be appreciated
