The forum discussion centers on deriving the transfer function for an RC circuit with specific component values: R1 = 47kΩ, R2 = 4.7kΩ, and C = 10nF. The transfer function is expressed as H(jω) = R2/(R2 + (R1 * 1/jωC)/(R1 + 1/jωC)). Participants discuss methods for calculating amplitude and phase responses using complex algebra, emphasizing the importance of manipulating complex numbers to achieve the desired form H = Hr + jHi. The conversation also highlights the use of software tools like PSPICE or MATLAB for generating Bode plots and analyzing frequency responses.

I have plotted the phase!
What do you think?

Thanks for all your help rude man!

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!
