Active 2nd Order Filters - The figures below illustrate using opamps as active 2nd order filters. Three 2nd order filters are shown, low pass, high pass, and bandpass. Each of these filters will attenuate frequencies outside their paSSBand at a rate of 12dB per octave or 1/4 the voltage amplitude for each octave of frequency increase or decrease outside the paSSBand __ Designed by Bill Bowden
Amplifier requires no DC bias - 03/16/00 EDN-Design Ideas Intrinsically capacitive transducers and or high-impedance signal sources usually require ac coupling and a buffer amplifier to condition signal for furr processing. Buffers take many forms, but most of m compromise signal quality through Design by John Guy, Maxim Integrated Products, Sunnyvale, CA

An Op-Amp based battery voltage Monitor - An ECU must have a way to monitor battery voltage. Here is a simple op-amp based circuit which will illuminate the LED when the battery voltage drops to a certain level. The turn-on point is set with R2. You must be able to vary Vcc (usually with a good power supply) to set the circuit. Decide at what voltage you'd like the LED to illuminate, and apply this at Vcc. Adjust R2 until the light just illuminates. Use an LED which will light at the desired voltage level, and determine R3, using ohm's law (E=IR), to keep the current flowing through the LED and op-amp to around 10mA.
