Say $\omega_s=1.96\;,\omega_p=0.785$ For bilinear transformation-:

$\Omega_p=2/T*tan(\omega_p/2)$

$\Omega_s=2/T*tan(\omega_s/2)$

Should I put my calculator in radian mode or degree mode. I believe it should be in radian mode but there is written ambiguously in my textbook(somewhere degree, somewhere radians).

  • $\begingroup$ Since the stop and pass freq given are measured in radian put it on radian $\endgroup$
