For RC, output across the capacitor is low-pass and across the resistor high-pass. For RL, output across the resistor is low-pass and across the inductor high-pass. Loading and source impedance are not included.
روش Calculation and راهنما
RC: fc=1/(2πRC); RL: fc=R/(2πL)
For RC, output across the capacitor is low-pass and across the resistor high-pass. For RL, output across the resistor is low-pass and across the inductor high-pass. Loading and source impedance are not included.
