Hello,
I am looking to easily substitute the complex number j*omega into the s variable within a transfer function that has been Laplace transformed.
This is my code, and I have poor matlab coding skills, I am sorry.
I have had to manually insert the coefficient values in another line "magT" because I don't know how to just directly swap "j*omega" for "s" in my "Transfer_func"
syms C R_1 R_2 R_3 L s V_o i omega%Equations
R_1 = 10;R_2 = 10;R_3 = 10;L = 0.001; C = 2*10^-6;Z_1 = R_1+L*s;Z_2 = 1/(C*s)+R_2;Z_3 = R_3;Z_23 = 1/(1/(Z_2)+1/(Z_3));Z_tot = Z_1+Z_23;V_i = Z_1*i+V_o;V_o = (V_i/(Z_1))/((1/((1/(C*s))+R_2))+1/R_3+1/(Z_1));Transfer_func = simplify(V_o/V_i);magT = sqrt((5.903*10^24)^2+(1.181*10^20*omega)^2)/sqrt((1.181*10^25-(2.361*10^16*omega^2))^2+(9.445*10^20*omega)^2);
