first op-amp merge two signal 1khz and 10khz
With different sin voltage level. after, this signal filtered with high pass in upper and low pass in downer active filter and extracted primary signals.

Nice idea to demonstrate filters. However, check the first opamp and flip plus and minus input, because "never use an opamp with positive feedback only, if you expect a linear behaviour". Keep it up!
