Design Notch Filter

Design a direct-form I notching filter that has a filter order of 6, center frequency of 0.5, quality factor of 10, and a passband ripple of 1 dB. Create a notch filter design specification object using the fdesign. notch function and specify these design parameters. notchSpecs = fdesign.

How do you calculate notch filter?

The formula for calculating the notch frequency is, notch frequency= 1/4πRC, where π equals 3.14, R is the resistance, and C is the capacitance.

What is quality factor in notch filter?

Quality factor is defined as the ratio of the notch or peak frequency F 0 and the 3 dB bandwidth BW . Mathematically, Q factor is given by Q = F 0 / BW .
