courses.physics.ucsd.eduis the amount by which & are out of phase. Impedance is the ratio and relative phase of voltage and current. The important point to realize can be thought of as a generalization of resistance in AC circuits. Taking a quick look at Ohm’s Law you might guess that the impedance of the resistor is …
Introduction to Switched-Capacitor Circuits

Filter Circuits - Northern Illinois University
nicadd.niu.eduFilter Circuits • Passive filters with a single resistor and capacitor are called one-pole filters. † The high-pass filter selects frequencies above a breakpoint frequency ω B. = 1/RC. † For small ω, A goes as ω or 6 dB/octave; φ = tan-1(1/ωRC); for small ω, φ approaches +90 .
