TDEV Generated by the bottom branch of the noise Model

 A similar analysis to that performed in section 6.1.1 allows the following result to be obtained for the TDEV of the noise generated by the bottom branch of the model  

$$\mathrm{TDEV}_w(f)\approx K_w\sqrt{\frac{1}{5B_n}\frac{0.3^2}{0.3^2+B^2\tau^2}}[ns]$$ (50)

Substituting B_n=5Hz into the above yields

$$\mathrm{TDEV}_w(f)\approx \frac{K_w}{5\sqrt{\tau}}\sqrt{\frac{0.3^2}{0.3^2+B^2\tau^2}}$$ (51)
