For the asymptotic Bode magnitude plot shown below, the system transfer function can be

Initial slope is zero, so K = 1

At corner frequency 𝜔1 = 0.5 rad/ sec, slope increases by +20 dB/decade, so there is a zero in the transfer function at 𝜔1

At corner frequency 𝜔2 = 10 rad/ sec, slope decreases by -20 dB/decade and becomes zero, so there is a pole in transfer function at 𝜔2
