Simple poles or zeros (1 + jωτ) or (1 + jω/ω o).ĭ. Moreover, there are only four distinct types of terms present in any frequency response function:Ĭ. The advantage here is that Bode (logarithmic) plots can be constructed from the sum of individual plots of individual terms. The product of terms in a frequency response function becomes a sum of terms because log( ab/c) = log( a) + log( b) − log( c).
While logarithmic plots may at first seem a daunting complication, they have two significant advantages:ġ.
