What is the transfer function of low pass RC network?

The transfer function of a low-pass RC network can be expressed as ( H(s) = \frac{1}{1 + sRC} ), where ( s ) is the complex frequency variable, ( R ) is the resistance, and ( C ) is the capacitance. This function indicates that the output voltage decreases with increasing frequency, allowing low-frequency signals to pass while attenuating higher frequencies. The cutoff frequency, where the output power drops to half its maximum value, is given by ( f_c = \frac{1}{2\pi RC} ).
