Band Pass Filter Circuit Diagram. In a band pass filter circuit the overall width of the actual pass band between the upper and lower 3db corner points of the filter determines the quality factor or q point of the circuit. The last part of the circuit is the low pass filter.
The best example of a band pass filter circuit is the rlc circuit that is shown below. The circuit diagram of active band pass filter is divided into three parts. Creating a bandpass filter from a low pass and high pass filter can be illustrated using block diagrams.
If the value of quality factor is less than ten then the pass band is wide which gives us the larger bandwidth.
The parameters of importance in a bandpass filter are the high and low cut off frequencies f h and f l the bandwidth bw the centre frequency f c centre frequency gain and the. If the value of quality factor is less than ten then the pass band is wide which gives us the larger bandwidth.
