frequency to radians per sample
Hertz to rad/s formula. The angular frequency or angular velocity Ï in radian per second (rad/s) is equal to 2Ï times the frequency f in hertz (Hz): Ï (rad/s) = 2Ï Ãf (Hz).he angular frequency or angular velocity Ï in radian per second (rad/s) is equal to 2Ï times the frequency f in hertz (Hz):
