Design of Digital filter using Bilinear transformation

The Normalized transfer function of a second order Butterworth filter is given by,
𝑯_𝟐 (𝒔)=𝟏/(𝒔^𝟐+𝟏.𝟒𝟏𝟒𝒔+𝟏)
Convert the analog filter into digital filter with cut off frequency 0f 0.5𝜋 rad/sec using Bilinear transformation. Assume T=1 sec.

Sir why here u are not used omega *T

[@yasminomar3090]

this is for high pass or low pass filter?

[@adnanshaikh7376]

Low pass
