Therefore, alpha band separation in the time domain can be achieved through the use of elliptic filter with a cutoff frequency of 13 Hz, while beta band separation in the time domain can be achieved through the use of Chebyshev filter with a cutoff frequency between 12 Hz and 31 Hz.
The primary LPF adapted 8th-order elliptic filter having continuous variable cutoff frequency control capability to reject peak noise components in the wide noise frequency spectrum distribution.

The design of compensating section starts with the design of elliptic filter, but with the ripple factor different from that of EMQF filters.
These performance numbers are based on a 12-section elliptic filter with two inductive and two capacitive non-adjacent couplings.
While achieving low insertion losses, enough harmonic attenuation was obtained by modifying the Chebyshev filter and the elliptic filter topologies to resonate at harmonic frequencies.
7 shows the simulated responses of the Chebyshev low-pass filter network, proposed low-pass elliptic filter net-work and standard elliptic low-pass filter net-work, respectively.
However, the high gain slope of elliptic filter is achieved at the cost of the higher Q-factor of filter sections, which requires complex calculations and accurate tuning.
If this filter were realized using a conventional elliptic filter the response would not be symmetric, 5 inductors rather than 4 would have been required and the minimum to maximum inductor ratio would exceed 8.
A combline elliptic filter comprised of coupled lines of metal bars and inter-resonator lumped capacitors has been reported.[3,4]
