FWIW, I think of it as the capacitor having lower impedance at higher frequencies. As the frequency component of a signal gets higher, the capacitor in the RC filter diagram above looks more and more like a piece of wire, thus allowing more of the signal amplitude to be developed across the resistor. At low frequencies, the cap … ron morris performance
