Can any oneanyone mention the transfer function of second order notch filter to remove the line frequency of 50 Hz, in terms of frequency and sampling rate.

Just like for Low pass butter worthButterworth filter as,

$$ H= \frac{1}{\sqrt{1+\left(\frac{\omega_n}{\omega_c}\right)^4}},

$$$$ H= \frac{1}{\sqrt{1+\left(\frac{\omega_n}{\omega_c}\right)^4}}, $$

where $\omega_n$ is the signal frequncy andfrequency and $\omega_c$ the cutoff frequency.

canCan any one mention the transfer function of second order notch filter to remove the line frequency of 50 HZ Hz,in in terms of frequency and sampling rate.

Just like for Low pass butter worth filter as  ,

H= 1./sqrt( 1 + $$ H= \frac{1}{\sqrt{1+\left(wn./wc\frac{\omega_n}{\omega_c}\right).^4); }},

$$

where wn=signal$\omega_n$ is the signal frequncy wc=cutoff and $\omega_c$ the cutoff frequency.

Just like for Low pass butter worth filter as  

H= 1./sqrt( 1 + (wn./wc).^4);

where wn=signal frequncy wc=cutoff frequency
