WebControlling Bandwidth. Any amplifier should ideally have a bandwidth suited to the range of frequencies it is intended to amplify, too narrow a bandwidth will result in the loss of some signal frequencies, too wide a bandwidth will allow the introduction of unwanted signals, in the case of an audio amplifier for example these would include low ... WebThe impedance of a resistor stays constant with frequency. For a capacitor, its impedance get smaller and smaller as frequency goes up. If R and C are in series, at 0 frequency the capacitor has infinite impedance (1/jwC = infinity), so it acts like an open circuit (we say a capacitor blocks DC current). The Resistor will have zero current and therefore zero … mngwl wrestling
