1. What features of a circuit design correlate to a passive, high-pass filter? An active, high-pass filter? (i.e. What makes a passive filter different from an active filter?)
What is the answer to question
23.1?
23.1 Active low-pass filter You can make a low-pass filter by putting a capacitor Cr and resistor Rf in parallel for Zj as shown in Figure 23.1. At low frequencies (well below the corner frequency), the feedback impedance is approximately Rf and the gain of a non-inverting amplifier is is 1 +R//R,. At high frequencies (well above the corner frequency),the impedance is approx- imately 1/(jwCs), and the gain of a non-inverting amplifier is...
