Butterworth Tee LC High Pass Filter Calculator

The Butterworth type filter was first described by the British engineer Stephen Butterworth.

A Tee filter is a filter that has a two series elements and a parallel element connected in the shape of letter T.

Butterworth filter are characterized by a constant gain (flat response) across the midband of the circuit and a 20 dB per decade roll-off rate for each pole contained in the circuit.

Butterworth filters are termed maximally flat magnitude response filters, optimized for gain flatness in the pass band. The attenuation is -3db at cutoff frequency. Above the cutoff frequency the attenuation is -20 db.

The Butterworth is the only filter that maintains same shape for higher orders whereas other varieties of filters (Bessel, Chebyshev, elliptic) have different shapes at higher orders.

A High pass filter is a filter that passes high frequencies, but attenuates frequencies lower than the cutoff frequency.
