Default band pass filters

i want to build a 6 different band pass filters using a switched capacitor on each filter and a pic to control the switches in and out of the filters. the purpose is to enhance the speech band of a radio signal by filtering out the noise. is there a standard design i can use? or if not what are the componment values of the filters (eg capacitors, resistors etc.)?

The capacitor and resistor values will depend upon the frequency which you want to pass.
