Web(35 points) An electronics designer has been assigned to design and simulate an analog active low-pass filter (LPF) for an audio system. Using a Sallen and Key (SK) topology as the core, design a Butterworth low-pass filter with unity gain providing a passband flatness of 2 dB across a bandwidth of 10 kHz and a stopband attenuation of 45 dB at 20 kHz. ... WebThe Butterworth filter (linear analog filter) can be realized using passive components and active components such as resistors, capacitors, and operational amplifiers with Sallen-key topology.

There are several different filter topologies available to implement a linear analogue filter. The most often used topology for a passive realisation is the Cauer topology, and the most often used topology for an active realisation is the Sallen–Key topology. The Cauer topology uses passive components (shunt capacitors and series ind…
