A high-pass R-C filter can be constructed by
simply reversing the position of the capacitor
and resistor.
At high frequencies the reactance of the
capacitor is small, and the short-circuit
equivalent can be substituted.
At low frequencies the reactance of the capacitor
is small, and the open-circuit equivalent can be
substituted.
A plot of the magnitude of Vo versus the
frequency.
