Can any one help me please?
A band-pass filter has an upper critical frequency of 15.00 kHz. Determine the bandwidth of the circuit

Hiiii,

Bandwidth of BPF is determined by this formula.
BW= fh-fl;
where fh is higher cutoff frequency and fl is lower cutoff frequency.
You have mentioned only higher cutoff frequency.
So if you have lower cutoff frequency you can calculate using the formula given.

Thanks
Amit
