tf1 = tf(num1, den1);
tf2 = tf(num2, den2);
tf3 = tf(num3, den3);
tf4 = tf(num4, den4);
...
tf10 = tf(num10, den10);
tf_series = tf1 * tf2 * tf3 * tf4 * tf5 * tf6 * tf7 * tf8 * tf9 * tf10;

Hi all;
I have tried using this cascade tf1*tf2...; but the bode plot provides me unexpected results.
Are there any known bugs?
