WebThe gain in the passband is , and the stopband drops off at −6 dB per octave, as it is a first-order filter. Sometimes, a simple gain amplifier (as opposed to the very-high-gain operation amplifier) is turned into a low-pass filter by simply adding a feedback capacitor C. WebThis tunable low–pass inverting amplifier circuit amplifies the signal level by 26dB or 20V/V. R2 and C1 set the cutoff frequency for this circuit. The frequency response of this circuit is the same as that of a passive RC filter, except that the output is amplified by the pass–band gain of the amplifier. Low–pass filters are often used in
