Bw fh-fl

Bw= fH – fL The difference between the lowest cut-off frequency and the highest cut-off frequency is known as bandwidth. To be an ideal bandpass filter, the filter has to filter or attenuate certain frequencies that even lies within the band because to eliminate noise. WebElectrical Engineering questions and answers. a. fC=fLxfH b. BW=fH−fL 3. Proposal Design. (20.Points] Using the same capacitors, give a proposal for the values of fL,fH and the resistances used in the band stop filter to be designed if we need to attenuate a signal which has a frequency f=1kHz. Consider Bw=500 Hz.
