Using complex number notation for the improved Pleiades microphone passive filters

For example if an inductor of 41mH in series with 140Ω is used to crated a gentle low cut slope the notation used is:


Pleiades (140Ω, 41mH)


So the x axis number is the real part of the vector ie resistance and the y axis number is the imaginary part of the vector ie inductance.


See next post on using such a filter while testing the MD211 N with the 7586 Nubistor electron tube on the Pleiades V6 head amp.
