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)
