Hi , I am designing a circuit that has a low pass filter, high pass filter and band pass filter. So far i gotten the low and high to work for the most part. They are individualy connected to leds. The low pass is supposed to come on at 100Hz, high pass at 10kHz, and band pass at 1k. The band pass is giving me trouble it deos not come on when it is supposed to. Attached is a copy of the circuit. Any ideas or help would be greatly appreciated.
