Hey guys, I've recently completed a module on circuit theory and I came across this particular slide on RL circuits (High Pass Filter) which puzzles me:
High Pass: RL Circuit, Low Pass: RC Circuit
The phase is given by:
tan ψ = (ωL/R)
but the very next line it is written as the reciprocal:
tan ψ = (R/ωL)
And the corresponding bode plots are based on the second (inverted) phase..
