<p>A frequency-dependent resistor comprising phase rotating devices each of which rotates the phase of the input voltage by 90° and is constituted by connecting a reactance load represented by a coil or capacitor to the output of a voltage-current converter. The phase rotating devices are cascade-connected to each other. The voltages outputted from even-numbered phase rotating devices are converted to currents and fed to the input terminals of the first stage.</p> |
