Hye all, here are my shcematic.Both of them doesnt work properly on the breadboard.I didnt see anything wrong with both of it.I conduct the experiment with audio generator as a input signal.The amplitude is set at 10mV.The first test is on the sallen key filter and 2nd is on the treble boost.Both of the circuit were test separately.
I put in a audio signal from audio generator and see the output on the scope.I started to increase the frequency and suppose the sallen key filter using TLC2272 will alter the signal above 3kHz.But the signal still appear at the output even i increase until 10kHz.
Same goes with my treble boost filter.It suppose increase the gain at the break frequency 10kHZ as i increase the gain from 100Hz but nothing happen as i observe the output at the scope.
At the first sight,there is nothing wrong with my circuit design.Theoretically,it will work as plan.May anyone comments on my circuit?
