A Chebyshev Pi LC High Pass Filter Calculator is a tool used to design high-pass filters based on the Chebyshev filter response. It helps engineers and circuit designers calculate the inductor (L) and capacitor (C) values needed for a π (Pi) topology high-pass filter with a given cutoff frequency and impedance.

Key Features:
Chebyshev Response: Provides a sharper roll-off than Butterworth filters but introduces ripples in the passband.
Pi Topology: Uses a configuration where capacitors are placed to ground at both ends, with an inductor in the middle.
High-Pass Filter: Allows frequencies above the cutoff to pass while attenuating lower frequencies.
LC Component Calculation: Determines the appropriate inductor and capacitor values based on input specifications.
Inputs Required:
Cutoff Frequency (fc)
Passband Ripple (in dB)
Source and Load Impedance
Order of the Filter (number of reactive components)
This type of filter is useful in RF circuits, signal processing, and communications to block low-frequency noise while preserving high-frequency signals.
