The effects of feedback amplifier characteristics on constant temperature hot-wire anemometer systemsThe 3rd-order analysis of Perry and Morrison (1971) was extended to 7th-order by Watmuff (1987) by including both the bridge-capacitance and the frequency-response characteristics of the feedback amplifier. In this paper, the bridge capacitance has been excluded from the analysis. The influence of the gain K, roll-off frequency f(A), and offset voltage E(qi) of the feedback amplifier are examined in more detail together with their interactions with the bridge inductance.
