An RLC circuit is an electrical circuit consisting of a resistor (R), an inductor (L), and a capacitor (C), connected in series or in parallel. The name of the circuit is derived from the letters that are used to denote the constituent components of this circuit, where the sequence of the components may vary from RLC.
In this work, A high pass filter is designed with selected values of RLC component to work with cutoff frequency 1 KHz which is demonstrated in the upper figure and the lower figure is the over all response of the HPF circuit.
