Band-Pass Filtered, Inverting -40 dB Attenuator, 10 Hz-100 kHz, 0.1 dB Error

Band-Pass Filtered, inverting -40 dB attenuator, 10 Hz-100 kHz, 0.1 dB error. An attenuator circuit is required when the magnitude of an input signal needs to be reduced. This version of an inverting attenuator features an easily tunable band-pass filter that is useful to limit noise and also allows for independent control of the dc output level. The circuit can be used in a variety of applications from low-level signal generation to large input signal attenuation
