How to use Bode plot with exponential complex funtion

Hi,

I need some guidance on how to use Bode plot with a formula like this one.

it's the exponential function that only has the complex part that i'm not sure how to write in matlab. I tried a few variants but just ends up with error messages. Otherwise somewhat familiar with transfer functions like what follows afterward.

Kind Regards

David

Hi @David Oestlund

Maybe like this:

R = 2;
C = 3;
G = tf([R*C 0],[R*C 1], 'InputDelay', 3)

G =
 
                6 s
  exp(-3*s) * -------
              6 s + 1
 
Continuous-time transfer function.

margin(G)
