Jolly good show indeed!

I have plotted the phase!

What do you think?

You're welcome.

Except I'm confused about one thing - your plots look 100% right but the expressions you allegedly used are not.

The phase is not tan^-1(1+ωRC) - tan^-1(1+ωR₃C). I suspect you used the right expression by accident or something similar. Check your Excel for the formulas you actually used.

BTW I wish I had your knowledge of Excel!

The formulaes I used are, which are correct right?

arctan(ω*R*C) - arctan(ω*R3*C)

Thanks! Wish I had your knowledge in physics!
