I am attempting to build an Op-Amp circuit in which a sinusoidal input is used. Below is the description: An active, op-amp bandpass filter circuit for audio frequency inputs. The implemented filter circuit must provide a maximum gain of 14 dB inside the pass-band and less than 9 dB of gain below and above the critical frequencies of 1000 Hz and 5000 Hz. Design and implement an LED indicator circuit that uses the output of the bandpass filter circuit as the input. Light a green LED when the frequency of a 1 V peak-to-peak amplitude sinusoidal signal is between 1000 Hz and 5000 Hz. Light a red LED when the frequency of the input signal is outside of this range. Any help greatly appreciated!
