Given a bode diagram
From the figure, I see that when $\omega = 100 \text{ rad/s}$ the magnitude response starting to go down and when $\omega = 1000 \text{ rad/s}$ the slope become higher. Then
$$H(s) = \frac{1}{\left(\frac{s}{100} + 1 \right)\left(\frac{s}{1000} + 1 \right)}$$
Then I tried to plot it on MatLab and here's what I got
The plot shape is close but both Y-axis are different. Where did I go wrong?
