Which among the following is a universal active filter?

Which among the following is a universal active filter?

a. Notch filter
b. All-pass filter
c. MF5 filter
d. Band pass filter

Correct Answer : c. MF5 filter

Explanation :

All the fundamental types of filters like low-pass, high-pass, band-pass,notch & all-pass filters can be easily designed with the help of MF% filter & hence, it is regarded as a universal filter.
This MF5 is a second order filter which has the proficiency in realizing shape-desired response in addition to Butterworth, Chebyshev, Bessel & Elliptic. MF5 is also renowned as sampled data filter. Its one of the characteristic feature is that it can be cascaded so as to provide steep attenuation slopes.
