Hello all,

Me and my group have a design project due next week(Nov. 8) and we currently have a working 6th order bandpass filter with various resistor and capacitor values and 741 op-amps.

This is currently being considered a 'B' project and I was hoping that someone could give me some ideas on what to do next. We have been thinking about having a variable gain but arent sure how to implement the circuit. Also we want to have it audio compatable, if there is a somewhat simple circuit that we can build soon let me know


Thank you for all your help!

 

Start by upgrading to modern op-amps that are rail to rail compatible.

Are you looking for ideas to modify the current circuit? Do you have a schematic for it?

Do you need ideas for a new and different project as well?
