Talk:Pole–zero plot

How bout Pole-zero plots in Continuous Time?

as Mykeknauff said, this page is somewhat misleading as it only deals with the discrete time case.

Why is it $$b_0 + b_1 s + b_2 s^2$$? Isn't it more usual to write $$b_0 s^2 + b_1 s + b_2$$? — Preceding unsigned comment added by 71.167.72.124 (talk) 17:22, 4 March 2015 (UTC)

Would $$ B(\beta_m) = 0 $$ be more clear than $$ B(s)|_{s = \beta_m} = 0 $$? — Preceding unsigned comment added by 71.167.72.124 (talk) 17:39, 4 March 2015 (UTC)

Should also write it in product of zeros/poles format, like $$H(s)=k \frac {\displaystyle \prod_{i=1}^m(s-z_i)} {\displaystyle \prod_{i=1}^n(s-p_i)}$$ but with consistent variable names and meanings — Preceding unsigned comment added by 71.167.60.72 (talk) 17:49, 4 March 2015 (UTC)
