Unlike a 1st-order filter, which rolls off at –20 dB per decade, this cascaded design achieves a –40 dB per decade roll-off. The output shows much stronger attenuation of higher-frequency signals compared to a single-stage filter. #ElectronicsEducation #electronicsrd #lowpass #filter #electronics #circuit | Electronics Education | Facebook
