Filter VC Filter 2 vCC VccPeak Detector VCC R3 R13 47:C1 U2 VCC vcc RT 0.1uFRS VM 10040 03 741 R12 C2 .01uF L1 VEE 74 R10 VEVEE R12 15.0V VCC R8 R2 2010: 85 % ko Co Input and 1st Gain Stage: What is the function of the RC configuration of Filter 1? What is the function of the first op-amp, U2? Band Pass Filter: What is the function of the band-pass filter of Filter 2? What is your calculated value for L1? 2nd Gain Stage: The second gain stage further amplifies the filtered signal after passing through Filter 2 Peak Detector: What is your calculated value for the capacitor in the Peak Detector Circuit? Buffer: What is the purpose of the buffer op-amp U1? (Notice what the path to ground would look like if the buffer was not present.) Comparator: Whaf is the function of the op-amp U4? What is the purpose of the potentiometer connected to Vn of U4? What is the general function of this BIT powering the diode? (ls it an amplifier, switch or source?) Page 4 of 5 Page 5
